AFK numbers rising

In my last 5 games there have been 4 afks.

The last couple times I have started up league I have thought to myself, "There is no way another afk will be in this game." But somehow, someway, it still happens. Against all odds it KEEPS happening.

And after every loss in my placements I watch my MMR tanking, knowing there is nothing I can do about it.

The days I go between playing games keeps increasing, because the more angry I get when i get another AFK player on my team. It is literally a waste of time and a huge inconvenience knowing that these losses will push my MMR down and will cost me dozens of games played to try and get back to where i originally was before I had to 4v5 every game.

The amount of times i've said "open mid" in these last games has been much too many.

EDIT:

My MMR (checked on op.gg) has gone from silver 4 to bronze 2
