Well an easy way I found to get XP without boosting or modding and stuff, I play headquarters. What ya do is, Your team get enough point to where You won't win the game by capturing the next HQ. Then you pick a very good class, Find out where they are spawning, then you don't push they're spawn, Just chill far enough away to were they keep on spawning in the same spot. When I do this I usually get over 100 kills every time, followed by almost 20,000XP without completing challengs. Completes challengs and you will get mad CEP. By doing all this I got to 7the prestige level 70 in 5 days playing time! Hope This helps you all. Thank the topic if it helped
