Coming from csgo what should i expect? (If you are any familiar with csgo you will know that valve matchmaking is unplayable due to amount of cheaters and the only way to enjoy 5v5s is faceit)

I was in a game earlier with all of my teammates and the opposing teams walking in a straight line and not moving the whole game and as soon as I won three rounds it auto surrendered for no reason. Does anyone have an idea of what this is?
