Inner Beast

[Kitru]

the big dmg only comes every 90sec.

And, since you can't activate multiple off GCD abilities simultaneously, it'll actually take between 5 (if you don't attack and just click the CDs) and 10 seconds (if you activate the CDs in between attacks) to get all of those CDs active. If you're using Inner Beast as an emergency heal, you've got a comparatively tight window to stack up all of the CDs required to maximize its effectiveness.
