let's say if you will 100% get a coin per game.
how many game you will need for one super elite? 150s.
how many game you will need for whole crew? 2100s.
if you will really play 2100 games for the crews, it would not be called inflation.
I guess this event is to give the free player a chance to play, so that,
the game does not become pay to win.
Game environment seems more healthy than those 300% exp - 400% exp event.
So, don't worry.
