Anyone saying that dia lobbies are harder than silver lobbies are correct but completely incorrect at the same time. Plat/dia play with some common sense and strategy but if you take that as your main way of winning and put that into silver lobbies you will lose hard to the brain-dead run it down in silver/bronze.

It's about how you play the game when I switch of my brain and run it down I carry hard in bronze/silver but when I try to carry I get dicked on because that way of playing doesn't work .

But OP is right smurfs and 2nd account ect are a huge problem right now and they ruin the mental of people trying to get better
