Stability's Good , GM's put you immediately to jail when you say something may be rude to them they are helpful but they belittle some players and treat donors better imo . some costumes are only obtainable via donation giving donors a little more advantage vs non donors . would rate donation balanced if they also put those costumes in cash shop available for coin purchase that you can get in game or even if it does not look as good just with the same stats, i'd rate the donation balanced.
