One of the hardest luck mobile games I have ever played as far as getting any 5 star characters. Extremely unfair whereas I understand you want to have variety and a long lasting experience, but it is quickly diminished by the obvious "pay to win" format which doesn't help because of the low percentage for 5 star pulls. Incentives for pulls suck major as well. Game play is decent and very fun....just wish there was more ways of gaining gems or better chances for draws.
