I doubt they'll have the balls to keep the elf restrictions. But I'm very glad they didn't throw this class out there to get mangled, and are sticking true to kit. That's super rare to see.
Death knights should probably have been like, human, dwarf, undead, orc. Dwarf is quite the stretch, but it's the only alliance race that really should have been added like that. Gnomes are silly, night elves shouldn't even be cannon as they have their own spirtuality all fixed up with wisps, goat-elves are supposed to be too pure... worgen and goblin are the greatest errors, however.
I get why though- there are people who only play one race, or like one race, and having the DKs restricted would reduce their popularity some. Demon Hunter has the same logic, but boy, I just do not care. So happy to see night elves rocking like they should. So happy to see the blood elves there, with their elven heritage mattering, instead of it just becoming "roll troll pve" or whatever. Such a good announcement.
