I have the same build as you and I have to say I don't use offering often, mostly for fun pvp and annoying high levels. don't get it if you don't need it. There're enough warlock skills to worry about. Unless you're urber at micro controlling weapon switching and key smashing, offering doesn't really help much. Not to mention the risk of losing 95% of your hp in an instant, which allow anyone standing near by one poke you to death. However, it is fun in pvp when you sleep your opponen, debuff and offer them to death

, its a good laugh when they start cussing at you about how offering is a cheating skill blah blah blah.
I would suggest skip it for now, and farm it at the cap.
