First of all, sorry about my bad english. I'm sentinel or controler (KJ & Brimstone) currently is Diamond 3, and I think I don't deserve my rank (not boosted). My aim skills aren't that good compared to other player in this rank disparity, but still somehow i manage to get pretty much always 15+k per game. I play both Solo Q and 5-stack games, I have same thinking but with same positive KDA. There is some times when my aim skill literally drops to iron, i drop full load of phantom and don't hit any bullet. You might say, play and you'll eventually get demoted. I tried that in Diamond 2 and now i got even promoted. My KDA doesn't show anything, I just think i don't belong in diamond elo.
