Problems with dynamic queue

When the system was first introduced, I knew I was not going to like it. Why? Because I'm the only one of my friends that have gotten above gold. That means I cannot duo with any of my friends. I know I could find people online, but most are very inconsistent and normally very toxic.

Down to the point. In the last 10 or so games, About 6 of them have turned out really, really badly.

For example, one of the more recent games i've played was shaco jungle. My team happened to be in a 4 man premade (Hint hint I wonder why hes complining?) I did my job, I invaded, and put the enemy graves behind taking both of his first buffs, I ganked mid, top, bot. Although no matter how hard I tried, none of my teammates could do anything. My bot lane would suicide into tower as I arrived, thinking they are mundo and will never die. Whereas my mid laner just sat there and farmed. I know games like this happen, and I'm not trying to justify that this should never happen, however towards the end of the game (about 16 minutes in when the 4 man premade gave up) They decided to all afk in the base. Now this is just completely wrong. I have two options at this point. The first is to afk like all of them and ff@20 to end the game. Or I can continue playing, and try to get them to keep playing. I chose the second option, and begin to tell them we can possibly win the score is only 3-7 and we are ahead in dragons. Their response? and I quote, "Report Shaco for negative attitude and toxic." Somehow the other team agrees and I get a little warning message at the end of the game.

This is just completely wrong and should not be happening. I'm fine with riot trying to make it more friendly for people to climb, but allowing a 4 man premade to decide the fate of a solo queuer? This should not be happening
