In SoD classic wow the new Honed Blue Dragonscale Leggings do not seem to exist. I’m only able to test this on Alliance but I havent been able to find either the leggings or the pattern on the AH or the nuetral AH(for what thats worth).
It seems like the other 2 patterns were placed where the originals were. The chest is sold by Blimo Gadgetspring and the Shoulders drop off Cliff Breakers in Azshara. The leggings were taught by the Dragonscale trainer. Currently he only teaches you the original Blue Dragonscale Leggings and not the honed version.
Theres no information about a pattern but my current theory is that it was intended for players to get the Honed Blue Dragonscale Leggings from the trainer. Is this correct? Is there a recipe not found yet or have I missed something?
