Ok here is something about the UDK
UDK's even under revised rules are still grossly overpowered. I fail to see why this hasn't been corrected. There are not enough "normal" heroes (being elite or legendary) that can counter this hero's powers. I know that changes have been made, but the fact still remains a UK in midlevel (silver) arenas can still be impossible to beat, even AFTER his whole team is dead.
I haven't tried live yet, but I know that the above is still true in TTA, one UDK and you can be completely screwed. I'm tired of this fact, and probably a lot of other people are. So far the fix the corrections by the additional heroes to counter the UDK doesn't fix the main problem, which is still he can stand up to an entire team (even an OP one) and cause a loss by time.
