you do know, that the druids themselves said that it makes your mp5 while casting the same as your mp5 while not casting, and while inervated and not casting, it makes it 400% more than the usual, so that means you'll get (and this is from my character with 166 spirit before buffs) roughly 120 mp5 with inervate up while casting (480mp5 if you don't cast). so yeah. completely useless. that's 480 mana over the 20seconds which is pathetic.
