I understand comms is important in this game but it feels like lol I’m low ranks where everyone just uses it to grieve. Is it ok to just mute anyone that just grieves?

So recently i ranked up from b2 to s3 mostly because of the improvement in my aim and crosshair placement but i fell that i cant rank anymore because i don't play good with me team(i am the problem) i can win a 1v1 and had a lot of clutches...
