Game Mechanics: Overkill should not count toward KS calc

[Droog007]

I can't even think of a way to prove this, but I'm 99% certain that on live servers you could not KS a mob that had less than 50% HP remaining. On P99, I can KS a 50hp mob with 5hp remaining if I BS it for 500. Extreme example, but I have seen it happen a lot - especially if I assassinate a mob that's more than half dead already.
