Two bugs which I can't find where to report, both in the same game (can't seem to register for the forum to report). In a game I played, somehow my weapon was duplicated (a weapon which is only in my deck once was in my graveyard and then my hand twice, yes I double checked to make sure I didn't make a mistake). However, on finishing the game, and buying a memory vial to record it, the link it's given me to the recorded game is to some random game 3 years ago.
Really wanted to like the game, and have been back and forth on it a lot. In theory, the mechanics of the game are pretty cool, but in practice the classes feel unbalanced, making some matchups impossible to win, and the rate of gold growth in particular means for anyone who can't put in significant time every day (and I've put in a few hours most days this past week or so), upgrading decks with card packs is not going to happen for too long a time to hold interest with the game itself.
Clan system is pretty bad too, no apply option, and IMO modifications of how deletion of clans works are needed.
Single player is reasonable, though very short (obviously work in progress, as the dialogue shows), and should reward with gold on first playthrough of each chapter, to give new players something to get started with.
