I'm with Havok83 on this one. Surge, despite having a drug using past, is not a "dark" person. Armor's powers don't reflect a dark character either.
Granted, Laura is supposed to have moved on from being dark though. Is she regressing in this book?
Surge should be leading a new XMEN team with Laura, and Armor should be the junior character in an XMEN book. Psylocke and Cable def work as "dark" heroes.
