So then, should we consider the possibility they WANT Gambit to fail?
If so, reasons?
1.) Fanboys of pre-existing characters (*cough*Wolverine fangirls *cough*) that resented Gambit's popularity? (this was clearly the case in the early 2000's, and the writer of Ultimate X-Men even outright stated as much)
2.) He's a problematic, cis-gendered heterosexual, handsome white male? (not exactly en vogue at modern Marvel)
3.) He's too tied to (the more popular among writers) Rogue, and constricts her usage.
4.) He's relegated to a mid-carder who still has hype to get new characters over. (All due respect to Liu, but, his inclusion in X-23 is an example).
