I wanna built an experience when it comes to teams and built a good connection with people we can have fun playing the game with

I have built a high understanding of the game around me through tournaments I have watched and playing with my friends in the higher ranks of the game. Hiwever myself I am a lower rank because I am either in a team with someone who trolls or i drop 25+ kills and we still wnd up losing. I tend to be effective with a sniper as well for example i have games with 15 sniper kills and in the past 7 days I have more than 250 kills with a sniper.
