When did werewolves ever have thralls?? Sorry just not buying it. Should be all weres on the team but different ones for different functions (ie, strong bashy blitzers, fast agile catchers and average linemen)
I was thinking that the catcher (or fetcher) type could have lower AV but get regen (and no claw, has to clip them so he doesn't deflate the ball

)
The blitzer type can be strong and decent AV but no regen, have frenzy, but no claw.
Have the linemen have average stats but all start with claw.
Just my thoughts, not sure what the actual stats would be or how much they would cost.
I just remembered there was a werewolf themed team done for one of the BB mags (I think, or was it one of the compendiums?) that was based on the Norse team. Maybe base the stats on a thrower-less Norse team and adjust the stats and costs from there.
Not sure how well that would work.
