Every enemy - boss, minion, or random - takes far longer to decide on a move, and to play that move, in wintertusk than it does any where else in the game. Almost two times longer, sometimes even three times longer.
I don't know if there are just too many cards, too much math, or what it is they're dealing with but it's making all battles slow, ponderous, tedious, and boring. Frustrating too. it's like they're all asleep or distracted or something.
