I’m so done with smurfs in this game

I was playing yesterday with my friends and I managed to hit diamond 1 and first game we play 2 of the players of the opposite team have season 12 SSL tournament winner and the other guy was a season 14 GC tournament winner, in what world does this even sound remotely fair? (My friend were plat 2). At first I thought they were boosted but when they started playing they were doing some crazy ass mechanics like triple flip resets and stuff like that. This is they type of shit that’s makes players stop playing the game
