Also, something that you had posted about earlier, concerning the roles being random. I think they are random, but tweaked. I have no proof of this, but I am fairly certain a game mod would want to make sure the game play was good.
I could not imagine all the power roles going to all noobs. I think if that came up randomly, a responsible mod would tweak it.
I also think that rb would be inclined to "spice things up" with his tweaking. I could be way wrong about this and really have no reason or facts to base this on, just my wild imagination.
