I agree with you completely and 100%
As it stands...the previous sets of new Mutants are/will be cropping up around Krakoa in various books like New Mutants and X-Men and the upcoming Cable so it's not as though these new characters are taking away panel-time and focus.
Lord Ewing *Praise His name! Uplift Him in song!* Your divine works will be remembered and glorified in worship for all eternity. Amen!
The Middle East is a region named from a colonial perspective and doesn't make much sense (what is it in the middle of? what is it East of?). There has been an effort to refer to the region as North Africa and East Asia because it is more accurate and specific. Middle East is still widely used, though.
