My main issue stays the same - The game isn't random enough. The minor issue of the economy (excess coins) doesn't bother me. Gameplay does.
PvP is beyond repetitive because you face few comps again and again and again. Yes, the same can be said about the actual Hearthstone but card games have innate randomness. Even if you play against a few meta decks their starting hands are different. Here you face the same stuff again, again and again.
PvE is repetitive, too. After you beat a bounty boss a few times, it becomes a boring grind. It becomes a boring grind even before that - when getting to the boss is easy (and requires same strategies) and defeating the boss is hard.
