I'm planning on removing blood magic once I have a couple blood magic gems, them I'm going to eat my mana with auras and proceed to use life to use my skills. I'm not sure if that will work out or not.... I think with act 3 out I have a few more passive skills, so I was also planning on getting the focus keystone for aura improvement.
