1.Destro and boomies need a slight / decent nerf(depending on the state of precog).
2.Precog needs a nerf/rework/ICD.
3.Melee Peasants need brought up to Ret Enh surv DH level.
No particular order:
Sub Shadowy duel needs tweaked
WW burst on RSK needs moved to sustain maybe slight dmg buff.
Arms needs crit dmg buffed somehow/10.0.5/7 Nerfs reverted, fury they can delete
Assa is outshadowed by sub but would be comparable once wizards/precog are toned down and Shadowy duel is changed. Outlaw needs buffed.
UH dk needs some slight anti caster buff - They are feeling pretty semi tanky vs melee again. FDK needs even more sustain and a defensive buff.
All caster specs are perfectly fine outside of destro and boomy.
except maybe devoker more sustain less burst.
All Pet specs need reworked or gutted.
Rets and Hunters and Ferals DHs are in a perfect spot.
Enh random 1 shot potential maybe moved to sustain. Very good though.
Aff is in a great spot and getting better each week.
Mages are good. Ele is quite strong but not over the top.
Hpal definitely and pres maybe need some help.
Rdruid is the most balanced healer and seems to be creeping up as the gear comes in. Rsham feel very good as well, close to mw, still a ways from disc.
This directly correlates with top 100 of each spec and their comparison vs other specs on the ladder above a certain rating.
