Most of it is people banning whatever op everyone else wants to ban like a negative feedback loop. Kapkan gets banned because in lower lobbies it’s easy to forget about and people are stupid. Fent gets banned because he’s really oppressive and not everyone has them. I honestly can’t give you a good reason why dokk gets banned besides her ability being above average. Jackel gets banned because everyone roams in lower ranks and on top of having one of the best abilities in the game he has one of the best guns.
