Same goes for draenai, they turned after the fights against the warlocks. Yet they should not be abondoned.
I understand your point, yet there are (for the draenei) some broken in the Exodar for example. Was it Nubundo? He was the main character in the novel Broken (found that one on wowiki, exellent read btw) and as Akama he slowly turned into a broken after fighting against the orcs and their warlocks.
For the body types. I agree, it would be a lot more work. Yet it would be nice, if they would give us a feature like that.
Always bothered me, that the priest next to me looked like an animal^^
