How to Disc: the way of negative-healing


Preamble, why you should use disc as I say:
I'm going to use the Earth, Wind, and Fire achievement as an example of why you ought to operate a disc priest as I do in a raid healing situation. This fight is still challenging for most guilds and puts a ton of pressure on raid healers. It has massive raid damage including chain lighting, fire, smoke clouds, and raid-wide stomp like effects. These often happen simultaneously, producing a perfect storm of wipe and carnage. It's in such cases, which amount to the worst cases, where the disc priest needs to stand up as the raid's savior.

When various sources of inc damage overlaps, traditional healing, or positive healing, is at it's weakest point -- this damage model defines the Earth, Wind, and Fire achievement -- and it will overwhelm positive healers. Only preventative healing, negative healing, can hope to save the raid when all the elements do their worst. This situation is your reason for being.

My ranking for Earth, Wind, and Fire is not as important as my arguments herein, but as best in class on WoL for that achievement, or 18th overall regardless of class, you can be sure my advice here comes with decent enough qualification.

Application:
This guide is about as "all purpose" as you can get with healing at a high level. It applies to:
This guide is not aimed at ranking on the scoreboard, it's aimed at healing the worst case. It happens that healing for the worst case brings out the best case numbers, and that stands to reason -- the worst cases demand the best performances.

Disc, how-to:
The first basic rule is a play-style point, it applies to any fight: never let a global cooldown go to waste. Overhealing only applies to positive healers, don't think like a positive healer. Unused shields (including DA procs) are much closer to unused fort buffs than overheals. So think of them as a insanely huge HP buffs which, if you can afford the mana, are never a waste.

The second basic rule is a gearing point, a proviso: never come to the fight unable to sustain the first rule. You need to gear for mana and regen. Your single greatest limit for increased HPS in a wost case scenario will be your sustainability, not your throughput stats. Even if you're on farm content remember that healing for the worst tends to bring out the best numbers, so apply this rule generally.
  • The play style I use and recommend should have you going near oom on all fights, including easy fights like Heroic Beasts and Ony.
Final Word:
Follow the two basic rules that I follow and recommend. This prepares you for the worst, which is what matters most; and it should garner you some top scores.

This application is good for easy fights like Heroic Beasts; progression fights like Earth, Wind, and Fire; and for fail-recovery or pulling the weight of others.

    1. Big question I have is your glyph of powerword shield only healed for 121701 (this includes crits) so your max theorhetical shields would be 1217010... yet your total guessed absorbs was 1.55~ million. obviously 300k or so was falsly attributed to pw:Shield so your ranking is borked. I only point this out because you proclaim how valid your post is based on rankings and best in class. Healing rankings do not reflect true rankings as a healer core of strong healers effectively nerfs everyone elses healing as there is only so much damage to heal.

      So your rankings mean little to add credibility to your posts and relying on them as such is only serves as a turn off to stroking your own epeen.

    2. Not sure why you'd want base absorbs on the glyph like that -- for one, the combatlog records the amounts absorbed which is what WoL uses.
      See http://forums.worldoflogs.com/viewtopic.php?f=2&t=903&p=3729&hilit=absorbs#p3730

      It's a fair enough reading. And the data is also verified by our WMO parse: http://www.wowmeteronline.com/combat/detail/272819634#healingout

      For your second point, you cant blame poor rankings on the greatness of one's fellow healers. Especially on fights like Earth, Wind and Fire, which dont allow you to carry poor healers. Many top guilds have high ranking healers, Vodka has a high ranked disc priest up there as well, and I'll venture most healing teams are not as strong as theirs.

      Chances are you bring too many healers and/or you're not as strong as you think you are. 10 mans may offer you a chance to let loose and get high rankings, since, if you're decent enough healers, you'll be two healing everything.

      More importantly, as disc, the bulk of your "heals" can't be nerf'd by having a strong healing team. I dont think you understand how negative healing works -- you can't snipe a shield.

    3. Did you fail math? The glyph of power word shield makes the heal 10% of the amount shielded (and can crit but I ignored this for the sake of simplicity). The amount healed from power word shield divided by 10% = the gross amount of the shields. So your shields can't absorb more than that amount unless you are saying the glyph is bugged. In reality the amount absorbed is even less as the criticl heals.

      Linking a 2nd parse to back up your information only further shows the discrepencies. The 2nd log has your effective hps 200 points lower and 200,000 total healing less.

      WoL also clearly shows that absorbs are an estimate. Blizzard did change the combat log but also in a recent post they said they wanted to improve this so that Shields could be correctly recorded.

      Shields are negative healing but they are also sniping heals. When you bubble a tank right before a paladin's flash of light hits then you nerfed their healing.

      You are correct more healers would lower each person's effective healing but there is still a finite amount of damage to heal or mitigate. My point stands that healing meters rankings are not a good measure of a healers skill/theorycrafting ability. Now take 2 healers on the same assignment in the same raid and you can directly compare.

      You are not even in the top 20 on WMO's rankings so once again like I said your healer ranking is borked and not a valid way to stroke our epeen. Sorry to deflate your bubble.

      Proof combat logs are not accurate on shields all the time..last line of the blue post. tyvm

    5. 1) There is no reason for GoPWS to equal PWS absorbs in that way. Preshielding the raid in anticipation of damage will garner shield absorbs on inc damage, but need not heal with the glyph at all. And vise-versa, you may heal with the glyph but have your shield fall off unused.

      2) WMO and WLO are never a perfect match, but they are close enough to show whether one is broken or not.

      3) WMO scoreboards were reset for 25man uldaman, for everyone including DPS, a while back. I was ranked class first for that fight as well (and many other uld25 bosses as well). Either way, my recorded HPS on that parse is still higher than the first ranked disc on there now (my ehps 5262, his 5145).

      4) I said you cant snipe a shield. Not that shields couldnt snipe a heal. But repeating this for me is not helping your argument -- just the opposite.

      5) last line on the blue post is in the WoL forum that I linked as well. We're all aware of it. So WoL and WMO estimate who absorbed what, and they both claim to be fairly accurate. Sure small differences between WoL and WMO will happen, but put together they should be close enough to reasonably rely on.

      Thanks for the interest in any event, but while your first response seemed reasonably well meaning the later one's seem to be 'reaching' for the sake of dispute. So you understand, I'll have to end the back and forth if it seems to go that direction any further.

    6. Ok lets argue 1 point only. Each shield you throw heals with glyph of pw:shield. That is a gross heal including effective heal and overheal. Some of those heals crit for extra healing while not effecting the heal.

      So your shield absorb amount is 8k the glyph of power word shield heals for 800. (10% of the amount of the shield). If it crits, it hits for roughly 1200 on a heal. Each shield has a finite amount of damage it can absorb and the initial heal indicates the amount of the shield or can be deduced through math (dividing by 10%).

      All heals have a set amount..effective healing is of course what is actually healed and then overheal. But the amount of the heal is the gross heal.

      So if the power word shield glyph applies 10% each time a shield is applied this is recorded in the combat log. If that shield is 100% absorbed we know the amount of the shield through the initial heal without the absorb ever being recorded in the combat log.

      In a perfect scenario you can take the gross amount healed and divide by .10 and you would know the theorhetical sum value that all of your shields could absorb. You could not absorb more than this amount as it is the maximum value of the shield. The gross amount of the initial heal of the glyph is actually inflated with crits since the shield does not critically shield. So the actual amount healed by GofPWSHIELD is actually more than could ever be absorbed.

      So when WoL or WMO records the gross amount of the heal including overheal(I did not deduct the crits but this would further show the results as false) divided by .10 is less than the amount recorded as absorbs the excess is in fact falsly being recorded as an absorb. This totally ignores the fact if you have overwritten a shield or a shield wasn't fully absorbed. I was simply showing the math of the MAXIMUM theorhetical absorbs. Anything recorded over this amount is clearly incorrect. The actual number would be even lower.

    7. Sure, so the GoPWS is 20% of the shield size. And so we times the GoPWS amount by 5 to get the shield size. 1200 x 5 = 6000, for example.

      Now, the overall total glyph heals, that's including its over-heals, is 419,112. (see the WMO)

      so we take 419,112 x 5 = 2095560

      The theoretical limit of my PWS in that fight then is 2095560.

      Note, you cannot get the theoretical total limit of PWS absorbs if you dont use the total theoretical limit of GoPWS heals, which includes its overheals. WoL doesnt show that figure, but WMO does

      On the topic of other healers in the raid changing data

      Yes, having more competitive healers in the raid does signifcantly nerf the healing output. But that's also like arguing that the better your dps, technically the less damage they should take from avoidable effects. Arguing effectiveness of a player is pointless in your argument, which isn't true.

      Adorno heals with people who have top parses on the world scale. Obviously him getting high rankings isn't because he's carrying the rest of his healers, it is because he is doing his job right. He isn't stroking his epeen (though he has room to), he is supplying numbers.
