Just a head's up on some things I've noticed. May or may not be intended and are current as of this patch week (13 November).
Garalon: Cannot pick up Pheromones when in Incarnation: Tree of Life. Confirmed this several times. Unsure on other 'Incarnation' forms.
Wind Lord Mel'jarak: Nature's Vigil will break CC's, including 'Spear' CC. I finally realized this after about the 5th attempt where CC's were breaking and me hounding CC'ers to keep a better eye on their CC--oops!
