And worst of all, the huge damage potential of deadly strike makes using other maneuvers too costly an option.
I think this is the real problem. Unless the number of dice in deadly strike is limited, all other damage sources wil pale in comparison, unless there really is a major advantage to non damage maneuvers ending combat faster.
I really think damage dice should not change, but be fixed, probably by weapon type, then limit the number of dice that can go into direct damage.
It's nice to think that players will try to simulate powers from 4e with ED, but in reality, I'd guess at least 70% of the time they will spam damage.
