Ok, so after reading quite few posts and threads regarding the healing capabilities of affliction - mostly people saying it sucks donkey balls - i have decided to make a thread and explain why affliction is most likely to really become to some degree the SL/SL of old.
There are few things we must take into account which are the following things but it isnt limited just to them:
1) Health normalization
2) armor normalization & no ARP
3) a lot bigger health pools
4) lower dps at 85 level
5) combat ratings sink with lvl 81+
6) % based heals
7) soul link being base
8) damage being balanced
9) Mortal Strike effect nerf
10) importance of Demon Armor + buff
Health Pools - As most of you know Cataclysm will be bringing a lot bigger health pools. People in ilvl 333 blues at lvl 85 have generally 85,000 health. We have to consider this a lot. Right now on PTR and Beta some classes are still having their damage changed and balanced. Due to that in some cases some classes mostly casters are capable of reaching 10k DPS bursts in pvp resulting in death in 3-5 seconds.
Combat Ratings - right now with overbuffed abilities which have yet to be balanced and with ratings fom end-tier gear, players can reach incredible burst and dps - also in pvp. When in cataclysm you level to 81 and on your combat ratings will drastically sink. What was 20% haste before cn become 4%, what was 30% crit before can become 6% crit and so on effectively reducing your damage output in comparison to lvl 80s.
Less damage at 85 - DPS/Burst will scale slower then health does for cataclysm thus if you do at lvl 80 around 10k dps with overinflated combat ratings and OP talents, at level 81 with sank ratings and balanced numbers youll o around 4-5k at most. By level 85 youll be able to pull around 7k dps to max of 8,5k dps most likely and that is under the perfect conditions thus almost uneachable in pvp environment. Having 8,5k dps in pvp at lvl 85 with 85,000 hp enemies would require 10 seconds of constant dps, prolonged by other pvp abilities like CC, heals, silence, etc.
Armor - with normalized armor, my warlock at 80 has ~6000 armor giving him 30% damage reduction against melee, with Demon Armor i have close to 37% damage reduction. This already on PTR helps A LOT against melee classes who deal pysical damage. The eason why armor is actually good now is the fact that Armor Penetration is gone from game. Now it can only come in form of talents or abilities thus making armor once again meaningful
Percent[%] based Heals - With no ARP, high armor, base Soul Link, Demon Armor, and huge health pools % based heals actually become very powerful. At lvl 80 PTR damage is out of control but that is subject for balancing. With hp at the level of 85k + and pvp dps being at around 5-7k level % based heals even if its just 2% from drain life become powerful tool and other classes need to make sure to silence/schoollock us to win. 2% of 85,000 is 1700 heal. Drain Life has 3 ticks, With haste we can have it around 2,5 sec level thus we reach 2040 HPS level. With Eradication up and soulburn effect we can reach under 1 seconds casts giving us quick health and incredible damage. With Death's Embrace when we get low we heal 5% instead of 2% meaning that 1700 hp per tick becomes 4250 hp per ticks and with 2,5 sec channel time we reach 5100 HPS.Now tell me this is low? You still think so ? Ok, throw in Demon armor or Improved Demon Armor increasing our heals by 20/30%. In 30% scenario our 1700 becomes 2210 per tick and 4250 becomes 5525 heal. Couple that with Soul Siphon and Haunt heal and potential Healthstoneand you have one fking touh warlock to take out. Just so you know, 5525 ticks with 2,5 channel are 6630 HPS
Soul Link - It's now base spell and with how easy it is to get demon back with soulburn or less then 5 sec summon for 0% mana if you got master summoner it aint problem anymore unless you're getting zerged or pummeled. Also Health funnel heals for incredible ammounts now. I had reached 5500 HPS heal on voidwalker.
Mortal Strike down from 50% to 25% - Now the old mortal strike is being changed and every class who had -50% heal now has -25%. The fun part is that if we have mortal strike effect on us and we have Demon armor [30% version] on us then mortal strike is theoretically decreasing heals on us from 100% to 97,5%. Now i am fully aware that without MS we would be getting healed for 130%, but most pvp is balanced around 100% so we are golden here. This change to MS alone will increase our survivability in PvP by A LOT!!!
Soul Siphon - it is still powerful considering Rated Battlegrounds, increased costs of dispelling and ability to SBSoC for mass Corruption.with 4-5 corruptions, ach scaling with haste and lasting 18 seconds, i really dont see heal from it as weak, if you get lucky streak youll get 8% hp return in just the blink of an eye. Seriously how is this weak ?
Demon Armor - more armor and +20/30% heals is a good thing, more so with nerfed MS.
TL;DR - learn to read long posts:P
With armor, MS change, demon armor, SL, % based heals and HP growing faster then DPS and dps sink after lvl 80, we WILL be toughest casters in the game to take down [as affliction].
TL;DR2
Healing as affli is fine
