So, this happens every single time.
But I noticed this happens only on Gold+, when I get demoted, there is some “balance” on Silver.
Just a while ago, I got matched against lvl 28, 36 and 57. None of our team was above 10.
As a League of Legends competitive player (Diamond 1) I sometimes rage against my teammates, I know they are new to the game, but what’s the point of not knowing the mechanics of the game and play competitive matchs?
On “Terminal”, I was playing Proxy, I planted the C4 and destroyed the wall. I went to plant on the cointainers and saw the map. The rest of my team were on the respawn, waiting for the enemy team. I told them “What are you guys doing there? Cover me while I plant”, their answer: “We didn’t knew the wall was destroyed, you’re too fast for us”
So, I went back, tried to cover them while they were moving and they keep dying.
I told a guy who scored about 200+ points, to stop playing competitive, to learn the game first. He just told me “stfu noob”. I played 2 another matchs, and got the same guy on my team. And of course, we did NOT win.
I know I may get a lot of Dislikes, but I just need answers 
What are your thoughts when you join a Ranked or Competitive match without knowing how to play the game?
