It's hard to accuse characters of being old as opposed to the New Mutants given they debuted 30 years ago.

Having said that I don't like this as a New Mutants fan. If the fallout from AvX is to be the destruction of the X-Men then the New Mutants should have become the new X-Men. These characters were always mutants first and the heir apparent to that title.

The current New Mutants book has gone a long way to portraying them as adults and not kids who need a mentor. So if Cyclops and Emma have blown it I think the New Mutants would rise to the challenge and rebuild the X-Men not become Avengers.
