If one went back 15 years Lorna was considered four things for games. #1 was a member of the X-Men. Next to that she was considered an Acolyte or member of the House of M. Last, but not least was as a member of X-Factor.
For Marvel promotionally at the moment treats Lorna as X-Factor, sometimes X-Men, and nothing else.
It would be even worse right now if Lorna didn't win the X-Men fan vote.
Magneto has it far better off as being promoted as a key member or the X-Men or the Brotherhood (or occasionally the Hellfire Club). It promotes the duality of the character and gives him two great identities in a way that X-Factor and sometimes X-Men doesn't do for Lorna.
I would like to see Lorna identified with an activist team again. The idea for instance of the House of M as a mutant activist family/team was a great seller for Lorna as a character, but until they fix their stupid retcon Marvel is not going to do much there as a selling point and they won't fix the retcon until the MCU decides to fix it.
