130ish Enmity reduction is lackluster at best when you crit for 600-700. Chameleon and nuke-managing is much more reliable. Wand-whacking at start while tank builds hate+invigorate will take care of your TP needs for the whole fight, so added TP is lackluster too. Also, I don't want to add another spell buff that locks me in animations into my rotation, especially for such a minor effect. And lastly, what skill would you remove to add Quelling strike in your bars?
