More AFK's/DC's in Promo's?

This is just a little something to get a few things out of my system, and a few other things I have noticed along the way...

Over the past few months, I have had at least 15 failed promo's or more, 9 in bronze II, and I don't even know how many more in bronze III... Something I have noticed, a correlation of sorts. Is that EVERY promotional series I have had, it seemed there were more a-holes and d-bags who would often AFK, and then your average disconnect occasionally. I feel cheated... because in most of these games, we come SO CLOSE to winning, and just because we don't have the extra 1 or 2 people, we lose.  I have a few games, to serve as an example.

This game here, Ezreal afk'd, as a result, being one man short, we only managed to hold for a few minutes after, me and my duo partner could only hold for so long, as he failed to prevent twitch getting fed in his own lane.

Darius lost top lane pretty hard, but the enemy was losing most of the game, later shen disconnected for a few minutes, setting us behind, then came back, which it seemed we were going to win, but one bad teamfight and one less man lost us the game.

My friend(Varus) did exceptionally well, but our top-laner (tryndamere) was afk from the start, it seemed like we could win, but yet another story of being one man short, and one sh*tty teamfight lost us the game.

Keep in mind, if memory serves, I have NEVER experienced any DC's or afks, except for people temporarily dc'ing due to ping for a few seconds, in games preceding that of promo's EVER. It is almost as though this is intentional... I'd like to hear all of your thoughts, and not the typical. "L0l you suck elo bronze scrub".
