As someone who actually -wears- blue facepaint four times a year RPing a Celt at LARP I want to agree, but I guess I have to be realistic about this, blue is an Alliance colour, Red is the Horde one, and well, the WC2 Elven Rangers did wear Red warpaint (Even though at the time they were fighting the Horde)
I mean, yeah, I’d love Blood Elves to be ‘Celted up’ a bit more, but thats me thinking of Elven legends from my homelands, not necessarily Azeroth Elves. I’d settle for Red.
