I think the jailers and the doc serve as an over-protective town. And if the yak yaks incorrectly d1, which there is a fair chance of doing, the maf are in a horrid situation. I'm not suprised this has a town win majority.
Amarok: This is why yak should never yak N2. At the end of the day, a good maf team should be able to work into two seperate wifoms (the stalker's and the convert's), and if they are able to win either of those then the game is theirs. The town win majority you speak of is 2-1, with only 3 games played, so that indicates nothing yet.
