Not only did people think blood elves were the most aesthetically pleasing race in the game, but Horde in general just has better passives that contributed to a lot of their progression.

Yes, nowadays you might see people rolling a night elf just to sweat and cheese some M+ shit, but those are very unique, tryhard cases. People would still rather play Horde because their racials actually have game changing effects in raiding (and PvP). Keep in mind that Horde guilds were commonly getting world firsts for years, so this also made the general playerbase want to play as Horde as well. Alliance, from a gameplay point of view, is pretty fucking awful.
