What the fuck are you talking about? I'm in my desired rank and played similarly skilled players to myself. I'm not boosted and I don't even have much of a desire to reach grandmaster. And when I play, I try to flex to what the team needs. I communicate and try to work with my team.
How the fuck are you even supposed to get better in this team dependent game if I'm not playing the only mode where people actually get on mic, communicate, and otherwise strategize? Even if you want to one trick, you can't learn to truly get good with that until you get a team that works with you.
This entire statement is stupid as hell and it's hard to even begin to unwrap it. Competitive mode is for people who want to play the game in a more serious way. But not so serious that they aren't allowed to play who they want. This isn't a fucking pro tournament, it's a videogame. You're supposed to have fun with it, competitive included.
So I very much stand by my statement. You are the problem. What you're doing here, showing contempt for anyone who isn't as good at a videogame as you, genuinely desiring a system you can abuse lower skilled players with, this is what toxicity is. If this is how you think and act because you want to win, then you deserve to lose.
