Oh, that was a given. I'm still so angry at that stupid retcon. It undid years of history and family drama and damaged what I believe to be one of the most interesting family trees in the MU. He def needs his on team- I loved his run on Uncanny for that very reason.
Yeah, that's my doubt too. He might leave it all behind. That'd be such a waste though- his X-Men knowledge alone is worth keeping around. And I hate to think what other writers might do with Magneto + Polaris.
I do agree it's been hot and cold. Couldn't care less about the Raksha and the Poisons, but I loved Mojoworld + Mothervine. Pretty much all of the issues where it wasn't all about Jimmy + the O5 are the ones I've liked best.
