Hey folks, update!
So - Dan and I have decided to play Magneto and Professor Xavier as NPCs and not playable, completely functional characters. We discussed their situations and the characters (their history, personalities and fan preference/admiration). We both think it'd be more comfortable for us if the characters were played when needed - much less stressful.
I hope this is cool with everyone. Dan was hoping to pick up a canon in replacement. We'll see how things pan out. Thanks folks,
