True that. Morrison introduced a bunch of potentially interesting students in Keratin, Contact, Polymer, Mentat, Slick, etc. and all we get are the ones I don't like; Glob, Quentin, Fantomex, Beak, etc. And very much a different 'generation' than the Academy X era!
I did not remember Armor appearing during the Kyost years, but I certainly didn't read every book and could have missed a lot! But still, someone like Dallas Gibson/Specter or Melody Guthrie/Aero or Andrea Margoulis/Rubbermaid or Kidogo (whose name I don't recall...), while very much third-tier characters, were still way more relevant to that era than half of the 'teen X-Men' they trot out from other generations.
