what the hell..

ok so you know the saying "practice makes you perfect".well i seem to have proven it worng. i dont understand why i keep getting worse and worse at crossfire. i used to be pretty good i kept a 2.0+ k/d until like 10k kills, and now its like 1.5 give or take a few. i have pretty good guns but i dont see why im sucking so much, i used to get ace most of my games and now im barely making a positive k/d score of the match. i guess i need a break from crossfire.. iv got good ping around 60 and pretty good fps as well..
