Trying to grind plat rn, and I’ve had 3 leavers in my last 6/7 games, is this common in plat or have I just been incredibly unlucky?

after playing for a while, im not sure if the only way to play is stealth mode or if there's some kind of agent ability that will help me in my always-pushing-in style. Can somebody lmk if there's anything that'll support my playstyle or is...
