In a perfect world, I completely agree with you. Unfortunately the majority of the online competitive games I have played voice chat consists of one dude giving helpful call outs while everyone else bitches and complains about why that dude sucks and their call outs suck. And even if it goes well it usually crumbles into a blame game by the halfway point. The only way I have ever been able to successfully grind a competitive game without losing my fucking mind is to just have friends to play with as we hang out in our own chat and mute the other teammates.
I truly understand where you are coming from. And that’s exactly why I don’t play competitive anymore.
