1. Survivors get the raw end of the deal at the end of the day. They get hung just for being a survivor claim. Maybe something similar to the mayor where survivor can hit the button and reveal as a survivor, or consequences like the jester, for instance those who vote a survivor guilty can't vote the next day.
2. My other suggestion is that psychic gets turned into a unique role. I've been in one too many practice ranked games with more than one psychic, which leads to town killing each other instead.
