Agree, I am amazed how these guys turned out like these XP's ..., I've been 1 week playing, 500 kills and still stuck in level 9 (25K xp) when someone as Cpl Her got kills as me(actually lower) and got x4 XP I have?
Either a glitch/buy they are using(THEY ARE BOTH FRIENDS, and when I asked scream, he said ask cpl) or it's an admin abusing.
