You're right of course. Old soldiers need to lay down their weapons after the war ends. But will the war ever truly end? How long can Marvel write sunny days before it just starts to get dull. I mean these mutants are supposed to be "hated and feared". If that's no longer true than what are the stories going to be about?
I guess I'm just a little chapped that Marvel changes the status quo to a better day for mutants right after killing off the guy that kept them alive during their darkest night. I can see why they think Tyke can fill that character gap. In the new order his characterization fits a lot better, but it's just not the same cat. He's way too passive in and out of combat and that was never Scott.
The mutants may not need a general but Scott was relevant before M-Day. He was a leader, a teacher, a motivator and a mentor. I see a place for those things in any incarnation of the x-men.
