Part of WotLK? Which part? WotLK was Dragons, humans, scourge, and forsaken. GNOMES had a bigger part in WotLK thank Elves did. GNOME!
Part of MoP? You mean the part where Tyrande got dressed down by Varian? Such import. Big meaning.
Yeah, lots of elves in Legion. Nightborne joining horde was so stupid…
BFA? I didn’t play it, but it seemed more humans and trolls than elves.
SL? Missed this one when current but leveling through it in DF I didn’t see much in the way of elves.
And as for TWW, if you’re talking about Alleria, good grief, man, she’s ONE elf, it’s not “Elves”. And she’s taking fewer spotlights than Andwhine.
