Empath and Wild Child have been in limbo for more than a decade, Empath since Bastion attacked Utopia and Wild Child since the original Wolverine Romulus story.
Most of the team is outsiders that have been in limbo for a long time, and are neither heroic nor fully evil. Even Psylocke (as Kwannon) could be put in that group.
I like these because I like the idea of mutantkind and its broad universe, not everything has to be about the same old xmen playing softball. and the writer probably won't have too much editorial meddling.
