The current beta build (15657) brought Priests our first cosmetic minor glyph.
Glyph of the Heavens – Your Levitate targets will appear to be riding on a cloud for the duration of the spell.
Well would you have your eyes open if you were standing on a cloud?
The cloud is dynamic which is a nice touch, fluidly shifting in size.
I can’t help wondering if it’s a bit big for Gnomes though. At it’s largest (as shown in the top picture) it’s about the same size as my Priest. Will I be using it when Mists goes live? Probably not, I find the movement a bit distracting and since I tend to use levitate mostly for leaping from the Lumber Mill to the Blacksmith, I’m not sure I’d want my arrival to be heralded by a large fluffy storm cloud.
