So 5 out of 10 characters featured on the art are an Alliance related race while 4 of them are a Horde related race. Alexstrasza is neutral since Dracthyr can be played on both sides.
They need to remake the art and include another Horde character. I vote for Kiro to be added so that way it will balance the factions.
Illidan is not Alliance. He never has been. Being related to someone from the Alliance does not matter if you are a neutral antihero/villain type. He’s not even night elf anymore, he’s half demon.
Xal’atath is not Alliance and never has been. Gul’dan is not Horde by modern definition…but he was part of the original Horde so I will give you that on a technicality. Which puts Horde ahead by 1. You need to check your math.
Better question why did they even put Alleria, Xalatath, and arguably anduin.
These 3 are only recently doing things in wow that are worth mentioning. If anything you should be seeing Malfurion, Kael thas, Cairne, Magni, madive, tyrande.
Technically only 2 are actually Horde but tbh would of preferred they had a character representative of all the playable races on the 20th Anniversary key art.
