Well, we’ve finally received word from Blizzard on the recent rumor on whether the Illidan quest chain (with its 80 Soul Fragments and all) is related to the legendary upgrade mechanic coming in 7.1.5 and Nighthold, and it was only a rumor after all!
We’re not entirely sure how this rumor got started, but it’s false – the 7.1.5 Legendary upgrades are not connected to the Illidan chain. https://t.co/XZyEDA6Mlp

As mentioned, it isn’t clear how this all got started, but it seems that the quest being missing from the PTR was enough to trigger some speculation and the Illidan chain connection somehow became the front-runner in the rumor olympics.
Hopefully not too many players frantically did the quest line on many characters due to the rumor, but hey, at least there’s some 870+ loot at the end of it if you did.
