Let me just say this is a beast of a CC, very impressive.

It handles multiple mobs exceptionally well, I don't even have to worry about HB2s desire to run through many mobs with this CC.
I do have a few issues.
It won't drink at the % I set it at. It will just stand around resting the mana, when the % is reached it continues on its way. If the mana gets really low, it will drink. Here is a screenshot of my settings and the log.

XP/h is just shy of 14000 at the moment, with all the waiting going on.
I have set it to use Hand of Freedom, but it never uses it. It just waits for the snare effect to wear off.
