I've been thinking that the minor glpyhs could do with something a bit more interesting and i think that maybe one of these would be a good idea.
Glyph of Feral Armor:
Provides the armor pieces granted by incarnation to become permanent too all forms at all times. provides no combat advantages.
Glyph of Natures Allies:
when Force of nature is cast it calls forth 3 treants/moonkin hatchlings/bear cubs/ferral kittens, to aid you in battle for 15 sec.
