I play the objective so i play as a team, The others dont pick the bomb or capture objectives. but i dont like to face against a team when. I would like to play randoms vs randoms. Its very unfair when you play against a 4 or 6 players who know each other.Ah so that's your issue. Your teammates don't play to the objective. What I recommend is finding a good team in a different playlist, partying up, and going into a game. I'd be happy to assist if you'd like.
You have both said to try and communicate or party up with players. What you and One Will No Way
failed to remember (though you have sound advice) is that this dude doesn’t speak English. I’m pretty sure most players either speak English or don’t use mics that much. (I know I never use mics unless I know the person.)
I don’t have better advice for you really. The only ranked I do is SWAT and I play that religiously. I think having really good headphones is essential for competitive gaming. So many games today have astounding sound quality where you can hear easily judge the distance and direction of gunshots and other noises. I’ve heard that their are some people who are blind that play Overwatch semi-competitively, because of the sound quality.
There you have it. Get some nice headphones. Very much improves your ability to game.
