each time someone asks to remove something from the game, the developers dont listen to it. they listen more to positive suggestions, like this whole mode was a suggestion made by forum user here. you must also understand, that while you dont like something, many people will still like this particular thing. and i think this role is fun.

captainkekw Perhaps there is a way to remove Dumbo from the match using a command in the game settings

it really looks that maybe in future it will let us customize game rules
