Hopefully mobs don't even aggro in 2.0 I don't want to be penalized for things like being stupid or oblivious to my surroundings. My friends and I might have to actually rally to overcome the situation. If i'm on a quest I don't want something like an enemy to be able to stop me. That's just a giant waste of time. I mean... I might fail the quest... and where's the fun in that?
