I'll sum it up. Lots of pay to win via buying character shards. Horribly unbalanced teams. Way overpowered teams that become the new meta for arena, if you don't have the new meta then you don't stand a chance. Characters that are so hard to get you might have 2 or 3 years in and still can't quite get them. Tons of pop ups on "sales", im talking like lots and lots of pop up ads every session.
