much of the mystery behind demon hunters will be revealed soon, but there have been hints that Illidan started this order way back before the sundering , just like Malfurion started the druidic order back then
if this is really true, we could in theory have highbourne demon hunters right? and what about High elf ones? Illidan got cosy with the Blood elves whom he led till the events of TBC that had Kael switch full allegiance to the Legion, and the rest of the blood elves sever ties with both Illidan and Kael'thas. So, would any high elves have made it to demon hunter ranks, cos identifying yourself blood or high elf is just a political thing right, and blood elf meaning has changed since the birthing day of the group
