I don't include the monster races because they're always going to be drastically different by default. I don't really count Lalafell when looking at "female body types" in FFXIV for the same reason. Their gender is potato.
I think most of this problem is probably a tech issue though where it's to do with making sure cosmetics fit characters with little to no effort. But I hate that, it's a cop out and these mmos need to be designed from the ground up for gear to be able to fit a wide variety of shapes automatically. Their internal tools need to automatically change the shape of the gear so they don't have to fit it to 10 races with a variety of body sliders instead.
I hate the hit box conversation. Just make the hitbox the same. It's a non-issue.
Anyway judging by concept art I'm not going to feel this way about GW3, but we will see.
