Ranking queue sucks

I can't believe that I had 2 games today in a row where in the first game the top lane and the mid troll the whole game and after that I try to have some fun playing another ranked and 2 players go afk but first they gave first blood just so we couldn't do remake. This is not the first time that this happens and I have heard that from many people so I please want a response of why the queues this season are so unbalanced. I'm plat 5 btw, not bronze.
