Theres my build, act 1 cruel, my main issue is my dps is like 140.. I went for a high hp build kinda like prozons but what can I do about my dps, I mean its fine for act 1 but will I be able to get through 2-3 with that dps?

Right now im trying to find gear with high ES and HP and im using freezing pulse with LMP and spell totem anything I can do to improve?
