On a double check, you’re right. There were some Worgen in the Grizzly Hills Wolfcult who were turned into Death Knights. It’s said that them breaking away from the Lich King gave back their self-control too. Whether that means they can turn back into humans like those that drank from the wells in Gilneas…Eh, not too sure. The Wolfcult was still led by Arugal, however. Or, well, a Shade of Arugal.
Worgen lore’s a bit messy. :\
To get back on point, I just want to remind that I’m not saying the larger KT models shouldn’t be available. I’m glad they’re there. I’d just like the inclusion of SW models too. Essentially: Why not both?
