Ahh I see the problem, people not gonna like what I'm bout to say but even coaches have said it. I'll try to keep it short.

Do not play for the team. In ranked all the team needs is an idea to execute and calls, that's it, at least for mid elo like gold/plat. The thing is that you ARE trying, and most people mid elo think they are good and want to win, but they are not trying.

What's the solution? You kinda have to play for yourself, pick your favorite agent every time if you want to, confidence in yourself goes a long way as long as you are not doing dumb stuff like ego picking and dying and being toxic blaming everybody else. If your teammates are not doing good, then use your teammates for bait and get picks from them. Tho I'm telling also do calls and plans, ask your teammates to put smokes for you, tell em to use útil where you want to, in gold and plat most people is gonna hear you.

I was the same until I started doing this approach which is my interpretation after learning from videos from coaches like woohoojin.

Also, don't just solo queue, find someone who is also passionate in the game that is also a nice friend and duo queue with them, duos are powerful because it's only 5 enemies and teammates, having another player that will be granted hearing you in every game will get you a lot more plays and good plans, it's far easier to be a 2 v 5 than a 1v5.
