They are the first of the troll Empires, the first of the troll tribes, and in fact, the first of trolls as a cohesive race. The Zandalari have seen it all, from the very dawn of civilization to the evolution of the night elves to the Sundering to countless wars to present day. They have been watching both the culture and the assorted tribes of trolls splinter further and further, into smaller and smaller tribes. They have been watching as their race continues down the slow path towards eventual extinction, with little choice in the matter.
The Zandalari are tired of watching. As some of the first known intelligent races on Azeroth, they have seen it all, from vast troll Empires to splintered sub-groups. They are not about to walk that path to extinction quietly. After all, there's another, far more ingenious option available. And although their first plan may have failed, their second plan is far more likely to succeed, given the strength of their allies of old. In patch 5.2, we're about to face off with the Zandalari for the second time -- the first being the revamp of Zul'Gurub and Zul'Aman in Cataclysm.
But who are the Zandalari? Why should we care about this random group of trolls over any other?
