In games like CS:GO They got a thing called warmup round. The nice thing woth that if they dont connect in 5 min, the match will quit and you'll not lose lp and u won't get an afk on your team. I know there's ways to abuse this a little, but it's better than risking having akf's in your game.
And u can warm a little up before the match starts and fix your settings. What do u guys think?
