Friendly faces takethe social role of the game. They talk a lot and make everyone feel good. This makes people not want to vote them out. They also get plussed a lot with their comments whic leads to minimal nomianation.
Advantages- There is nothing they can really mess up on. As long as people love them their work is done.
Disadvantages- If they come across too friendly or jusy weird and annoying. people will have no problem voting them out. also they are no match for a strong enough alliance.
