Climbing and DuoQueue

Building on two of the old staples of how to climb: You're the only constant, and if you're good you'll climb, I have to ask - Does DuoQueue upset this?

DuoQueue essentially confirms that you're always going to have two players of relatively equal preparation since the better player in the Duo will likely correct the other player until equilibrium. If that's the case, I can't outplay that. I'm in Bronze 5 and it's honestly jocking to get the least worst player. To put a finer point on it, you almost want the AFK player because it decreases the chance of feeding.

If that's true, should I be devoting my time to playing with a player equally interested in climbing.

This is a sincere question.
