Eh. I'm not calling for their deaths, but I do resent the ones that step in and take over roles already filled by existing students. I don't have a mad hate-on for Eyeboy, but I've read him through three series now and just don't care. Nature Girl I'm starting to come around to because Nadler and Thompson are doing a take where her personality actually seems influenced by her powers in a way more profound than what you'd see from a newly-converted vegan's Twitter. But Glob and Quire? Newp, they can go and I won't miss them.
It's not like the NXM are dropping dead from unavoidable circumstance; readers aren't railing at lightning strikes. These characters get left behind because writers choose to prioritize other characters, which leads to less exposure, which leads to the older crew being considered expendable. And then writers choose to kill them off.
