More like temporary teams for events that are completely randomized. Might get others to know each other more. Also, I'm doubting the organization of actual teams in DA. e_e Prove me wrong. I don't know where to start.
Events for Slifers only to mingle, duel and meet new people. Ideally they--we-- should have our own chat, since really, everyone else have their own clique and Slifers are not invited, which is kinda why a lot of Slifers leave after a couple of weeks methinks.
