When I read that the defending team is controlled by AI and loosing with this team also matters - suddenly all the nerfing made a lot more sense. So in a way the developers could have spared themselves a lot of trouble explaining from the beginnen why it is necessary. Just saying "because of PvP" what really is no traditional PvP didn't make a lot of sense.
So the devs got a lot of shit for the lack of communication. I feel partly bad for it but how the hell could we know what their plan is. Also creating almost indefinite possibilities to fight other combinations of toons adds definitely to the game and I'm looking forward to it.
What seriously needs to be adressed is the QA before releasing an update.
