Frenchy's take:
Sling some "COAD" that awards exactly zero, yes, ZERO (as in the number between -1 and +1, the number you just don't divide by) perks for any kills of players who constitute >5% of total player kills. FIXED.
Or perhaps maybe perks should be RANK based. Killing a noob in tempest is as easy as killing a noob in a P-40. Now killing Joachim, or fester in anything...that's an achievement. So change the perks to..
Perk = [Bandit ENY/ Your ENY]*[PERK multiplier] *
(3^([Bandit rank-Your rank]/1000)]/(1+ABS[Bandit rank-Your rank]) This would result in PERK RANK MULTIPLIER that would equal to 0.01 for a bandit with a rank that was 3000 below yours, effectively making shade vulching a waste of time.
It would result in PERK RANK MULTIPLIER that would equal to 1 for a bandit with a rank that was equal to yours, keeping near equal players at the same perk system as today.
It would result in PERK RANK MULTIPLIER that would equal to about 7 for a bandit with a rank that was 3000 above yours giving a nice bonus for noobs killing the games top aces.
The result would be to reduce the perks for top killers and highest ranked players since they are always higher that everyone else. Hre is the PERK RANK MULTIPLIER curve
