The Nerubians are awesome.
I like how they’re not above using morally dubious tactics to succeed against their corrupt queen. I feel compelled by all three main characters that you can earn reputation with and I had fun doing all the side questlines in AK.
This feels like a Warcraft faction, it is Wotlk tier in my opinion.
Contrast them with the boring kumbaya centaurs in Dragonflight, or most of Blizzards writing lately which feels like goofy fan fiction.
Even in TWW the Earthen are way too humanized compared to how they were in Wotlk and other previous iterations of the game.
The Arathi are supposed to be Vanilla Scarlet Crusade tier zealots but they have zero edge and I think people like the idea of them and their style and architecture far more than their actual implementation.
