I dunno if opponent level/your level would work, cause once people get to like level 40 and 50 then a 5-10 level difference is almost nothing again. I like a per level thing, this doesnt hurt early levels where you need to hit people a few levels lower if you arent a donator because your weapons aren't necessaarily the best they can be. anyways, something along the lines of 2.5% compounded per level difference would be my vote.
