We're not going to be making this easier. The challenge is supposed to be hard, but not insurmountable - remember, all the mafia members are using suboptimal teams that are going to be fairly easy to counter-team once you guys figure out what's going on. The two-battle rule is there to ensure no one gets far enough due to luck, like what happened last time (*cough* RT *cough*...just kidding. But seriously.)
The point of this exercise is for the community to get together and help each other form strategies to defeat mafia members (and we ourselves will help you build better teams, if you ask). If I don't see you on IRC talking to other players and seeking out help, I'm not going to have sympathy if you get 6-0'd by RT's CB Vileplume.
