Yes rogue was in blizzcon, no I agree. rogue needs a buff, god bless this thread is so right. Rogue is a mediocre dps when compared to every other melee in current game.
For Assasination:
I would be happy if they make poison bomb an active ability with a 10 second cooldown. A more controllable on-demand aoe+st ability is needed for us as most classes have a st ability that cleaves.
Or if damage dealing poisons can stack 3 times ( effect and base dot) this would bump dps for st, aoe and pvp situations.
