Since, as most now know, Namorita is "alive" and well and existing in modern continuity since she was "saved" by Nova (Rich Rider) in the REALM OF KINGS and again in the THANOS IMPERATIVE sagas, she needs a new place to continue her adventures.
With all the AVENGERS titles out there, and with nearly every hero (and some villains) now on an Avengers team, why not bring Nita aboard one of the continuing titles? I don't think she fits in with the last line-up of the New Warriors, and most of her former friends are Avengers anyhow, as was her now lost love, Nova.
