I decided to try to tweak "Classic mafia"

I like the setup, but it seems a little unbalanced, so here is my try at it.... Any suggestions would be welcomed..

My reasoning for role changes:
Mafia seemed to get screwed over a lot, so I gave them a boost with Stalker... Not sure how much that will help...
And I like Bodyguard more than Doctor, so yeah... We'll see how this works out...
