We need a new major glyph, that would change the role of our treants.
I mean boomkin, and cat, should be able to glyph their Force of Nature talent, to change their behavior to healing treants, or tanking treants.
It would be very useful for soloing content, and perhaps even useful for some raids.
Resto should be able to glyph his treants to make them do dmg as well.
Guardian could use dps treants too, and obviously - healing ones.
