So they are removing a lot of 7.2 stuff like 880 Nethershard gear (new currency for 880(BoA) & 910 gear, vendor moved)
850 nethershard gear (BoP tokens), still sold on Broken shore by Warmage Kath'leen
Also a soft "reset" of blood of sargeras, basicly with a new Reagent "Primal Sargerite", also combined with Obliterum to make Primal Obliterum.
New herbs/ore/gems/leather/cloth etc.
Blood of Sargeras vendor likely stays, and can be still used for current materials, not sure if they will add a Primal Sargerite vendor, but that's possible of course.
Thoughts?
