I mean, Blood elves being mana-hungry, extremely pragmatic, and commanding the Light instead of having faith in it is definitely Horde-like.
Also, once again Blood Elves aren't Horde because of Garithos; he wasn't even brought up in WoW. The reason is because the Alliance ignored their pleas for help for 5 years and it was the Forsaken (who are part of Horde) who helped them.
