I would say to add more options to copycat. I don’t know if that was the right way to out this, but let me state my request. Copycat cannot copy most neutrals and impostors either the exception of a few (Arrogance ➡️Reverie). It also cannot copy a handful of crew, but adding on that trying to copy an impostor or neutral that can’t be copied, kind of gives them away. Now, this is not 100%, but I have seen it be used. A way to handle this would be to have copycat change to a random crewmate killing role when copying roles that can kill (Impostors, Neutral Killers) and a random task based role when it copies other non-killing crewmate based neutrals (Jester etc..). Having closely related roles that Copycat may convert into also would be nice:
Vulture, Cleaner, Medusa: Mortician (use of bodies)
Jester: Retribitionist (Trying to get voted to die)
