Honestly? New ones should be added. Also if you ask me, one remake should be done. The Wotlk drakes look stupid because we sit on their neck. We really should sit behind their wings, on their backs, like with cataclysm drakes. (And I mean the start of wotlk drakes, not the Ulduar ones, Proto-Drakes). Rusted Proto-Drake is still my favourite mount!
