An idea for a new role called "Double Agent". You are a spy, you forge alliances and betray them as you see fit. The game doesn't allow for this type of play without violating gamethrow rules, so I wanted to create an espionage role that allowed you to betray people without violating rules.
Basically you're a neutral benign investigator who detects exact roles. You can find a mafia and then send PMs to them, informing them of doctors and sheriffs that haven't revealed yet. You can also blackmail jailors or kidnappers with your information if you are caught, and you can hide under the ruse of a "survivor" claim as you are neutral benign. You can side with town and find mafia, you can find one mafia and appear good only to feed mafia the identities of the doctors and sheriffs, you can feed mafia some false info to send them into a veteran, the possibilities are endless.
I wanted to make a role that increases in excitement depending on how creative the player wants to be. The capability of this role is greatly varied by the skill level of the person assuming it. It would give veterans an opportunity to spread their wings and newbies an exciting element to play with. You could actually blackmail someone, instead of just pressing a button, such as "Yes you can execute me, but I have two doctors in my last will. You really want to do that?"
I really want to emphasize the detect exact role, it's crucial to this role's success. The point of this role is to have information and to do with it how you see fit. While the Double Agent uses the mechanics of the Investigator he is not one, as he has no goal other than to survive. Information is his weapon and his defense, it will keep him alive by forging alliances and secure him the win by knowing things others do not.
