Here is a big problem with current X-Men stories, they seem morally drag down other established super heroes to reinforce this whole "mutants vs. the rest of the world" narrative on the rest of the MU.
This wasn't the case in say the 80s or the 90s, but it seems like the case now. Wanda is now a genocidal maniac, ditto with Black bolt, Captain America comes off as somewhat irresponsible and a something of a dick in AvX (though frankly I thought both the X-Men and the Avengers were behaving like A-holes in that story). Does Cap act like this in own title? I don't think so, so really it seems like their involvement in X-Men related stories drags them down and makes them inconsistent regarding how they have traditional been portrayed and how they are portrayed in their own titles.
Should Ms. Marvel be ashamed that she got her powers from T-mist, should she become super angsty? Should Spidey and Daredevil start murdering mutants, just to reinforce the "mutants vs. the rest of the world" narrative?
I'm beginning to think the X-Men are better off in their own universe and the rest of the MU would be better for it too.
