What you do here is you "cut" your enemies and let them come to you. Healing is all done by health globe. So be aware a long fight is doing you no good. All of your attacks can be stacked into 1 spot directly in front of you.
Worked pretty well in Act3 where you don't have massive mobs spiting fire or charging at you. Act2 and Act4 you are doomed. But that is just me, If you are wondering what kind of defensive status I have you will be surprised I was able to clean Keep2-3 in MP1.
