All these long posts when you can sum it up as “night elves don’t get nice things”.
Hyperbole aside, if kaldorei had all the logical allies they had in WC3, and all the Wild Gods they’ve worked with in the past backing them up, they would be a faction unto themselves and the Horde would never even breach Ashenvale. It would be March of the Ents: Feral Killer Elf Edition. So in order to have them lose, they need to not have all of their lore powers.
