Agreed, I'm all for making Vengeance super over powered but that won't happen, and realistic buff would have to be minimal. Ssfish has a good idea in another thread, to paraphrase/throw in a couple of my own ideas, using shatter or impale stacks a buff called rampage that increases rampages proc chance by 5% a stack and is consumed when you do proc. Something minimal like that would be awesome, although maybe not helpful in PVP still.
