The problem is that if Black Panther is the only way for black writers to break in at Marvel, you risk damaging the character. Why? Because what you’ll be getting is a bunch of novice writers who may not be used to dealing with the hassle of working for the Big 2, or writing comics period, getting put on T’Challa and potentially having very rough starts. The first couple of issues are crucial, if a writer starts weakly, it’s rare to be able to recover from that. T’Challa should be a character like Spidey or Bats, a “big” one that you need to prove yourself before you get the ongoing. Don’t mind newcomers auditioning for T’Challa via writing tie-ins or whatever elsewhere, Redjack did a great job on the King in Black tie-in, but I don’t think the ongoing should be the first place a writer should be writing the character.
There just needs to be more opportunities for black writers to break in at the Big 2, but who knows if that will happen?
