I prefer Retribution & Salvation since I don't use EE armor & prefer heavy weapons and of course I use EE heal charms in ACC slot. You will come to your own conclusion that fits your style of play. Oh, I don't mind using Revenge, Retribution & Salvation, I keep Revenge at 48% (only 3 points) and distribute others to Retribution & Salvation, I am not too fussed on 3 abilities. I am not used to it.
