Even the changes for the Unholy (Scourge Strike damage +7.7%) seem laughable when viewed outside diseases buffs (I would've liked SS/FS/DC buffs, than diseases).
I don't understand Blizzard: they have all the numbers, yet they think Ret DPS problems will be answered by a 1min reduction to AW? Sustained DPS doesn't mean an average over time, with distinguishable highs (arguable) and lows. Sustained should be achieved through increases on most/all abilities used in the rotation: CS, J, TV (especially) and HotR for AoE, from 20% to, let's say, 50%, to make it viable from 2 targets up and also by removing its condition to have a current target and to face it (highly annoying). OR make it spread Censure from SoT (lowered dmg/tick, even depending on how many targets are affected, for balance purposes; too difficult? they did it with 2 diseases.. :P) and get rid of SoR (seal swapping isn't a quality of life goal, for me).
I do not think these are unreasonable or impossible to make. They change much more for other classes/specs, so I believe they're more afraid of making Ret paladins head-of-the-pack so they prefer the opposite.
