Make single-position roles un-favorite-able

[BaneOfGiygas]

Alright, I'm starting to see what you guys are getting at. I'm almost always seen playing these kinds of single-position roles *coughAIcough* so I could understand why I don't see very much of this. Maybe tweaking the formula a bit to give priority to people who didn't play AI/Captain/whatever in the previous round but want to this round would help as well?
