I've reached 10,000 points in a crit server, the one area where you die by everything in a single shot almost. I wasn't even tryharding. I lost 40 points and seriously, I can understand you want #1 or something but it doesn't do anything special besides ego or hate which is why I reset it. I can understand it's frustrating but you shouldn't care for them, it only makes the game un-enjoyable.
I get targetted as rank #1, insulted for no reason. I reset it, I don't care about it. Hell, half the time my whole team isn't even doing anything helpfull! Instead of... crying about losing 1000 points in a single session, I just laugh it off.
What I'm trying to say is, stop caring about ranks, it makes the game not fun since all you'll do is only play for the ranks.
