I'd leave everything as it is, all very well to get feedback for something but the rules are done and this thread is about choosing a Star from the list supplied. Don't go chasing everyone's ideas, it's your tournament. You'll never make everyone happy.
I voted for the Jason Friday. The other two are crap as already pointed out (bomber guy is AG2 and the blunderbuss guy is only useful for fast moving teams) and Chainsaw DP gives everyone a chance to kill stuff, which is what this games all about, right!?
