I actually feel a bit sorry for Coates to be honest.
Imagine using the Black Panther solo book as an avenue to pitch ones obvious ability to write Storm really well and solidly in character at T'Challa and Wakanda's expense, in the hope of using the BP solo as a stepping stone to writing an X-title or two, only to have Jonathan Hickman come in out of nowhere to take over rewriting the entire X-Verse.
All that wilfull destruction of T'Challa and the BP Mythos was all for naught.
Coates just needs to get the frak off of further trashing the BP mythos and go sit his a$$ down somewhere.
