Post the role you think ruins the skill needed to play the game.
Mine is the Sheriff because every game I see something like this...
7: "Herp derp I'm Sheriff 9 is Maf, let's lynch him."
9: "No you're exec."
7: "OMG town you all suck, I'm Sheriff and he's Maf."
4: "Oh herp derp let's all vote him!"
9 is put on trial.
9: "OMG you idiot town he's exec!"
7: "No role, guilty."
9: "I'm doc..."
7: "Obv Maf."
9: "You're all retarded."
9 has been lynched.
9: "Wow wtf."
7: "Maf is so nooby this game."
Sure there is the need to make sure there isn't a Framer, but even if there is a set Framer in the setup the town will still lynch you based on a random Sheriff's lead... They just sheep the first lead they see...
This is why I put in an Invest instead of a Sheriff...
