Yeah I am a little confused as to the reasoning of why blizzard felt like soul shatter, fel flame, carrion swarm, and drain soul needed to be removed. Well maybe not fel flame so much I know they stated less cast while moving, but still why not just increase its mana or lower it's damage it didn't hit that hard to begin with and wasn't really being complained about in pvp.
the other spells i listed really don't seem to have a reason behind their removal. soul shatter was very useful. how are warlocks suppose to drop aggro now? and why remove drain soul from affliction? or carrion swarm from demo? button bloat was never really an issue i heard warlocks complain about. and those abilities didn't make warlocks op so why remove them?
