Well, the only memebers the Team who joined prior to her who haven't been confirmed to have received a League invite are the ones who quit the Team, so I wouldn't expect her to have done anything more special than say, Zatanna or Superboy.

In all the talk of why she was put on the Team, one point seems to have been ignored: It was an inevitable consequence of Icon joining the League. There is currently no precedent for a sidekick of a JL member not to be offered Team membership, and no good reason for Rocket to turn down an offer. So the real question might be: why was Icon added to the League? I think we got that answer at the end of Alienated. We'll probably be seeing him in a significant role later on. Rocket could have just been a side-benefit.
