I actually really hate among us's other roles for the crewmates and imposters (examples being guardian angel, shapeshifter and etc). They honestly just make the game more complicated than they need to be and removes the simplicity this game once had. Plus things like the guardian angel are pretty annoying since it allows the dead players to still interact with the game and help the crewmates win. I feel like they shouldn't have any input directly since y'know, they're dead. There's probably more i'll talk about but i'm already in a lobby rn :P

They have to add new stuff, to somewhat make game fresh. It doesn't mean it is good stuff, but they still have to.
