Stay calm. Improve as a player.
Which is exactly how I play the game.
But you can keep complaining about everyone around you and criticising everyone else. Even spin it to claim you are trying to help.
Just because someone makes a mistake, doesn’t mean they need you to tell them that.
Still find it funny that you think you belong in a specific rank, and I agree with the video that probably explains a lot.
But instead of typing about it, go and prove me wrong. Personally, I think you are a Plat player, because you are in Plat. Just like I am a plat player, wolfie is a silver player and so on.
