stamina has been a deal breaker to me. 300 max only lets me clear 2 areas, then its waiting for 600 minutes...
Paying for mercenaries is cool, but at level 21 i 'could' have 3 mercs but fighting doesn't even pay enough for 2...
finally, like above, game start slow and gets worse fast. play for 5 min then i have to reload or game gets stuck in combat
