Does unlocking Zandalari trolls require the raid?

[Rhielle-sentinels (Rhielle)]

Indeed! According to WoWHead, You DO have to RAID to unlock the new Allied Races in 8.1.5

Again… not what we’re experiencing:

Unless they sneak in a new achievement, it does not going off the PTR. It requires Exalted with the Zandalari Empire, Zandalar Forever, and Tides of Vengeance(Which is obtainable WITHOUT doing the raid quest. You are given the achievement upon completing the quest prior to entering the new raid).
