In a comic, every team member can and does contribute. In a forum battles, teams are generally just filler material because we take the top showings of the big hitters who, if written normally, wouldn't be hurt by anyone but the other team's big hitters. It's why Cap actually does stuff on teams with Thor or Sentry on them, for example, or Green Arrow with Flash/Supes/etc.
So this fight is basically BB vs. Warlock, with possible caveats from a few others. I like Warlock more often than not in that scuffle, though, and thus the IW.
