From the profession overhaul, no profession recipe is supposed to be class specific anymore. The recipe could at least be BOE so that a shaman can buy it and send to the players scribe.
In Legion, all glyphs are no longer class-specific for inscription, except for
Technique: Glyph of Flickering
It is sold in Nagrand by a shaman only vendor. Please fix this. It is the only class-specific profession recipe in the game, and should not be here post profession overhaul.
sold only by shaman vendor: Elementalist Sharvak
