To be fair, they are just now finally fixing the whole spine clipping through undeads cloaks thing. Heck, they never went and fixed all the issues with worgens during the cataclysm-bfa iteration that had literally teeths clipping out of their mouths and weird body horror type body stretching with certain animations. D: So who knows when they will actually fix em.
Honestly, Blizzard should just shamelessly let the community fix the bugs or do the customization for them if they show they are capable of doing so, with the main art teams approval before going through with it. You see threads all over the forums addressing all these character specific bugs and customizations with their own sub list of things to add in to the customization list. Heck let me take a crack at it Blizzard. Add me to the dedicated worgen community art team. I’ll add in some of the cool worgen options people post in threads such as this one myself. ;D
