Revenge Bonus

So when someone kills you, and then you kill them, the announcer is all like "REVENGE!!" and that's it. Maybe when you get a revenge kill, instead of just hearing "REVENGE!!", you get some sort of extra reward. Maybe 50% more bones, or 50% more gold, or both. So if they have 0-3 bones, you would get 3, not just 2; if they have 4-6 bones, you would 6, not just 4; and so on and so forth.
