Hearthstone is your typical p2w game which is fine to play on pc, but the mobile version has too much problems (bugs, lags and dc's) In order to minimize the problem you have to relaunch the app after any game mode, be it battlegrounds or standard. Updates is the most annoying of them all, although the pc verison is updated a few hours before mobile, mobile will take longer to update even after from the play store. I'd give a 4 on content and a 1 on the platform, on average 2.5
