Definitely a pay to win style. If you want to keep up with all of the new characters, it can be costly. The latest event couldn't be finished unless you paid over $2,000! This is insane! They aren't looking for players to spend time on the app. Otherwise it would be Free to play friendly. They're looking for players who spend money on the app. DO NOT PLAY THIS GAME if you don't want to spend thousands of dollars!
