Convoke is SO good, even as guardian.
Have a moment to get away from mobs? Drop form and heal THE ENTIRE 5 MAN TO FULL.
Boss facing away for a mechanic or casting something, like most frequently do? Go cat and throw out insane burst.
Need another defensive CD? Stay in bear and max that rage bar with some self healing for fun.
Huge fan of this ability, i feel like a hybrid again.
