Because your 6.75 encompasses less than two full games of rumble, so I assumed you weren't actually touting that k/d as a meaningful statistic.

well check clash

Again, good k/d but that's another game mode you've barely touched, and probably don't play much because you don't want to risk lowering your numbers. I'd be more impressed if you had, say, 1000 kills (and therefore a lot more games under your belt) and still managed to maintain that high a k/d. ~100 kills is not a big enough sample size to tell much of anything, to say nothing of the fact that neither rumble nor clash is as competitive as trials or any of the 3-man game types these days.
