For me, I think the writing follows.
Faerin is an ethnic, disabled woman likely in large part due to inclusion efforts by Blizzard. This is more emblematic of a deeper rot within Blizzard that then flows down to the storytelling which is going to be more centered on Modern Attitudes instead of what feels right (or just cool) for WOW lore.
Poor storytelling is a bit more difficult to wrap your hands around and easily present to others as evidence of this rot so the much more easy-to-display totems are used instead, such as a magic purple floating wheelchair.
