I'm simply saying that instead of making rankings based on kill to death rates make it kills-deaths (like the moh score) multiplied with your kill to death rate so having a high kill to death rate means your score increases much much faster. If it was just kill to deathrate all the top rankings would just be people who hardly touched the game and maybe has 20 kills and 1 death giving them 20:1 which is kinda hard/impossible to have if you have gotten 1000 kills.

Example:
A: 1000 kills, 200 deaths. Score: 5/1 (or just 5) x 800 = 4000
B: 4000 kills, 2000 deaths. Score: 2/1 (or just 2) x 2000 = 4000
So because A has a much better kill to death rate his score is the same as B's even though as MoH style score player B should have had more than twice as much because he played much more.
ok thats still a dumb way of doing it.
A is way better then B by the way he is playing right now. If he were to keep playing he would be 4000-800. Which is way better then B. Yet with your way they are created equal. So it should just be Kill/death ratio.
And you said it's cheep if someone would be 20:1 from not playing a lot.
But if you do it your way that would be 20 - 1 = 19 x 20 = 380. that just made his score even better then what it was before.... The reason you wanted to do it your way to make a person that never plays score worse. but you made it better.
