One in a hundred games is normal, players use alt bots to feed yourself fast, or just bots who spamming surrender all the time. No matter in which type I play, I see the same behavior and it is spread like a plague. The weakest accuse others of their own mistakes and then spoil the game. I think that RIOT sh1ting in its head, doing nothing to stop this plague.
What is your impression in the higher rank, the players doing same sh1ts?
