Wowhead has an amazing spread of the cosmetic glyphs that are coming to the game.
These are items like the impressive hunter glyph of fireworks.
The other one that immediately jumps out at me is the glyph of zen flight. Monk flight form basically. Very cool.
Mages get the short end of the stick a little bit. I’d much rather see a glyph that adds a polymorph rather than simply replacing the sheep. I like the sheep, darn it!
The rest don’t inspire much comment from me, but that doesn’t mean you shouldn’t go check them out yourself!
