Yup. I lose a lot of points frequently. But that's the point, right? The people who are high up are damn good. why? They will (basically all the time) lose 25 points per death, and get about 2 points per kill. That means that they have to have a kill ratio of about 13:1 in order to make that up. Of course, weapon modifiers matter, and not EVERYONE is going to get 25 points from you... but It's a challenge.
Other high ranking people can back me up on this, or tell me if it's true for them, but my kill : death ratio Is pretty inaccurate. A lot of those deaths were from when I was a lot newer at this game. My ratio is just coming back to 1 now, but if you were to take a snapshot of me playing now-a-days, it's not uncommon for me to have something like a 5:1 ratio. The other day I had a 32:2 kill : death ratio.
what I find is you earn the rank you have. You have hit the point where it starts to get much harder for someone to progress in the ranks, and that's good. Now it gives you a challenge. It means that when you get up to the top 100, you know you are good. So have fun in-game, and don't worry too much about stats. when you get better, so will your stats.
