-Use spy plane// counter spy plane// blackbird// you may not think so but in the long run you'll get more kills this way while it also will affect your teams performance thus bringing your W/L higher.
Don't forget, spy plane is 100 exp added, + after so many uses you get that bonus such as 100 times used, 500 times used... You can get easily 3-4 spy planes in a match, so 3-4 hundred experience, do that repeatedly for 50 matches lets say, and that alone is 15k-20k experience. Now that is't including the bonus that you may along the way as there are a few for 1000, 5000 points.
Just helping.
