This would be nice. I don’t have problem with the bones showing unless it’s the kneecaps so I wouldn’t mind being able to only hide those. However, it seems a little unrealistic that they’d be able to pull this one, specially as you described it as in, one option per bone showing and not coming in a “set” (ex.: “Hide both elbows”). And yet I think it’s far from viable since that alone would multiply the options of Forsaken by much more than what any other race has available.
The NPCs in Zuldazar have a straight back so yeah, it would be nice to have this.
No, I’m completely against this, specially since the nelf and human models are involved in this. If you want a dead human/nelf, play a DK. We don’t need Alliance models on horde, not anymore.
