The problem isn't money, the problem is winning. Cops right now are winning events, and if a cop leaves because he gave his two lives and is bored, there are still 15 other cops staying to fight because recently cops have been winning. I personally have heard less complaints about federal events within this month of September than ever before. It was disincentiviing people form wanting to play cop just get 4 v 10 at bank off cooldown and getting hammered.
