Gingerbeard and Princess Portal feel OP. Princess Portal especially as she can do loads of damage with a low power value.
Mass Destruction and Light Warden feel underpowered. MD doesn't do anything useful, LW too squishy.
I farm them all simultaneously, focusing more on gear I need than shards because gear has become so insanely grindy. If that was your goal with the patch, mission accomplished.
Spending the stamina feels worth it, but spending diamonds for extra chances does not. The drop rate for items should be higher in elite though.
You only need 5 good heros to be competitive. I feel like I have too many to upkeep.
Gold, gold, gold. Then more gold. And then maybe some more gold. Skills are retarded expensive.
