Some people have been doing this a lot lately. I am going to add this comment to make my peace leave it because I do not like dealing with drama.
San’layn are the extreme of both the Blood Elf, Kael’s troops that fled to Outland before returning for vengeance, and the Forsaken, people who where raised by the Lich King against their will and forced to serve, fantasys.
If ANY faction should get them, it should be the one that has both these groups and ONLY the faction that has both. (Horde)
If anyone is going to be petty and say San’layn should go Alliance as some kind of demented revenge for people disagreeing for requesting High Elves or as some kind of attempt to keep darker themes away from Blood Elves or as some kind of troll or to bait drama, you need to just stop it.
That kind of of behavior is unacceptable and it is being cruel to fans of San’layn and those themes for no good reason.
It is perfectly acceptable for Horde players to request this and is NOT okay to try and steal their ideas to Troll/Harass/Get Revenge/Block.
“Void sometimes is red!” is not a good justification. “Alliance already has Goth Elves” is not a good justification.
Stop it and move on.
