Beatdown and Vandalz are established. Armada seems to still be recruiting. Looks like there's at least one more coming into being, comprised of osumainfan, Bling, atomic, huafc, midway, and searat. That would make 4...if all Reapers are looking to get on a team, each comprised of 10 members, then we've still got 2 more teams to make. i played last night with Infamous Biker who seemed to have a squad of reapers that were all pretty familiar, so perhaps that could be a 5th.
