Basically...
-Lost Berserk entirely. 30% potency buff every 60s for 20s is gone.
-Replaced with an "enhanced" Inner Release. Halved duration, makes spenders free, causes all attacks to be autocrits. Autocrits won't make up for the loss of 30% potency and you lose at least 1 Fell Cleave per burst phase. Burst phases are now 10s instead of 20s.
-The potency increases to everything else do nothing. They mitigate the 10% loss in Storm's Eye dmg buff.
-Unchained is now POTENTIALLY usable with Deliverance but I'm not holding my breath.
Overall I wouldn't be surprised if WAR sits at the bottom of the tank DPS pile. Not to mention it's going to be the most boring of all 3 tanks to play.
