Yeah I think nuMags works best in an ensemble where is no-fucking-around style works well alongside the more innocent X-Men. It's a shame they're spinning him off and darkening his character, he was the best bit about Uncanny lately.
tbh I actually liked that portrayal because it was more a comment on the character and comics in general "we can't keep doing this, it's stupid". The way I read it was that Xorn was such a promising character and then OH NO it's Erik again lulz. IIRC by this point in the run Morrison was experiencing difficulties with the editors was was in a generally dark place, so it's him saying "OK this is what you want, go fuck yourselves" which I quite enjoyed, it was a bit punk rock.
