This game could be more fun if the drop rates where more balanced, the events are rediculous. They expect you to pay to win and the cards you need never drop. In the early stages they expect you to spend hours tapping away because the chests drop cards for things that aren't unlocked yet. The sad part is there aren't even any offers for the cards you need. There's no way to link your account to Google or Facebook to save your progress so spending money is a waste of time.
