This is a huge deal to anyone who uses inscription to make money. Milling herbs into ink is one of those tasks that limits your production capabilities, and can't legally be done while afk. In fact, the milling grind time (four clicks, and until now, eight seconds per stack of herbs) is one of the reasons I rarely advocate new auctioneers getting into selling glyphs. In addition to generally overcrowded marketplaces and auction house campers, it's a business that requires almost super-human patience.
This will probably make the glyph market even more crowded, as the amount of unhealthy AH camping you can do with a finite amount of playtime just went up by a fair bit.
