I really wish the matchmaking factored in your individual performance during a game. If your KDA was 35-18-5 and your team lost, I really don't think you should continue to have your overall ranking lowered and be matched up with more of those players of that skill.
Also, there's a situation that occurs in CS which is occurring here. Namely when you and a teammate are behind a wall or something, and you know there is an enemy player around the corner. The teammate near you will jump out to try and get the kill, and they instead get killed. They then lose their shit on their mic and berate you for "doing nothing", "not helping", "baiting", or whatever it may be. Of course, they took it upon themselves to peek and go for the kill, made no announcement they were doing so, yet completely lose it and go after you. This is happened to me multiple times in CS, and it just happened in Valorant.
I'll either be reloading, looking a different direction, or just waiting for the enemy to appraoch instead. And the teammate will jump out, get killed, and excoriate me for it as if it was my fault he died. I don't know if people are just looking for someone to blame but this is a recurring scenario that drives me crazy. Now, if you asked me if I wanted to rush it and I said yes, but then didn't, that would be different. But that's not what's happening here.
Had something similar to this in a match earlier. They wouldn't shut up on mic and it was 1v1, so I was thrown and died. They did not handle that well. It wasn't even the last round or anything.
On top of that nearly every round they ran in and got toasted leaving me alone.
