You dont see the problem. I tried what happen if i put a super tanky team (+ressurecting ) to live arena. End result 30 minutes game. I bet the opponent enjoyed the battle, when his enemy wait to last 1-2 sec to turn and delay the time.
No, I haven't seen the problem. I've had only 2 battles go past 5 minutes and none past 6:30. That's why I said above I'd back out of this discussion.
