I'm plagued by unbalanced duos

Literally the past 7 games have all had an unbalanced duo on one team or the other. Meaning a gold was playing with a bronze or a higher gold was playing with a low silver. And that lands a bronze or a low silver on my team. And that abnormally low player lanes against the abnormally high player, and its a no contest loss.

This is ridiculous. Balancing a team around the average ELO just doesn't work. You only have 5 data points so that's barely an average at all. And with the laning phase as crucial as it is, there's no way to keep things even! This is crazy. Sometimes you get a game like that, but I'm getting them every single queue. It's so annoying. Especially because the matchups have not been in my favor. That means my games are pure luck! I'm so frustrated here...ffs.

@Riot - rethink balancing games with disparate duo's. This is unfair and annoying.

You can say all you want about it being up to the team, but when a Gold 2 riven plays against a Bronze 2 garen, that team gets an immediate, strong advantage. I even captained the game to keep everyone friendly, and we almost won. But this is too many games in a row to go unannounced. Why is this happening?

UPDATE: 12 days later, every solo q ranked game has had a duo in it. Every duo has been disparate.
