Why do i keep getting queued with duo and trios?

Its a real fuckin killjoy to get paired against duos and trios game after game. Of course they are going to trounce the scrublords i get paired with who have no teamwork and only think of themselves. These goobers are probably sitting in skype talking eachother up and communicating in real time. Its getting really god damned tedious and taking a lot of the fun out of the game when you're always fighting against multiple people who have better teamwork than you just by virtue of queueing with others. Those people should be shoved into their own queues.
