Don't get me wrong, for the first time ever I feel interested in the O5 (Bunn, Molina, Magneto as mentor, Jean as leader and gay Iceman), but they should be more the X-Factor or New x-Men book.
Weapon X being the X-Force type book with probably X-23, Fantomex, Sabretooth, Lady Deathstrike and Deadpool.
Then Generation X with Emma, M, Jubilee, Chamber, Banshee and Legion for example.
It would leave the Blue book with Rogue as leader and Psylocke, Gambit, Bishop, Dazzler, Archangel and Northstar probably as casts members. Who wouldn't love that?
