Come on 3 out of 3 promos have AFK's?

Look I understand the idea, if you're getting trolls or AFK's on your team, there's the same likely hood the other team will have them, but that seems to be part of the problem. In all three promo games there were AFK's for a decent portion of the game, whether on and off throughout, or leaving at the beginning or near the end. They were also mixed, 2 of the occassions on my team, one on the enemies, and it's not as if I'm yelling I should have been promoted if not for the AFK's as I didn't play particularly well.

Problem is, you don't feel like you're actually able to do anything with these AFK's, nor does it feel satisfying when you win because of an AFK. I play ranked to challenge myself, not play games that are impossible to win or lose. These losses/wins are almost completely out of my control, and just leads to frustration in the player base. I'm not really sure what the solution is, but there has to be a better solution than what is currently in place.
