I don't understand what you're saying.
However, what I can tell you is that Rainbow items are complete and utter garbage. Epics of your class are BY FAR superior. My winratio against people in full-rainbow gear is 100% unless they AND their gear are at least 30 levels above me (aka they have full, fresh Rainbow gear), and since I'm starting to be above level 270 not many are 30 levels above me anymore.
Even then, do I care if my winrate is 95-99% against them? Not much. And since I got myself a HC legendary, you'll probably need to be 40 levels above me now. AND have fresh gear.
tl;dr; Rainbow items are garbage - forget about them. Use Epics, you'll do FAR better. Better yet, get a full set of HC Epics and respec to HC once you can.
