I’ve unlocked all the AR’s on both sides, and sad to say to those who only play horde, you are so wrong when trying to compare the unlocks of the Kul Tirans and the Zandalari.
Both require to do the 3 zones and the story arc, however that is where the similarities end. For Kul Tirans, you have to run all 4 dungeons as part of the Jaina arc which is required, then run the final dungeon (which had to be done in mythic form before they changed it). After that, you then have to run around the zones as it’s final part.
For the Zandalari, you require only to defeat the last boss in a raid and can complete it in LFR which was a joke. Next all you do is a few quests in the capital city, a very localized area. You don’t have to run any dungeon as part of the story arc, nor did you have to run the end Mythic dungeon.
For the Alliance, we required more work and effort for our Allied races. Even the Dark Iron dwarves required to run Motherload to unlock along with a very long run around back and forth quest chain.
