I love Claremont, but if I'm being honest, I'd like to see him just retire. His ideas and concepts are dated, and often not good, and his style doesn't gel anymore imo. This franchise doesn't need to go backwards, and bringing him in isn't going to fix anything. I don't want more of the Neo, never ending mind control, tentacles, or more of R'Chel.
But seeing as how he might be sticking around longer, just give him a solo or something. Don't need him on a team book.
