the free move team ability confuses me... does someone with willpower and that team ability get to move for free, then attack twice?

and yes this is my first post... so I'm a noob.

No, it just means that a move action by JLAvengers does not count against your action total. For example, a 300 point point team gets three non-free actions. A move action by Wasp would not count against that total.

However, the move action still gives the character a token, and characters can only take one non-free action per turn.
