Changing my review to 2 stars...WHY GET RID OF COOP? Don't you want more play time on your game? I like the concept of varying difficulty for each floor but we shouldn't lose keys for winning a floor. At least that would make it a little better. Give us some challenges to earn keys!! Also some of these factions make some cards WAYYY too powerful and basically forces a certain meta. There's barely any reason to use most common cards. They of all cards should get talents first, NOT legendaries.
