Valve has released an update to fix long queues for certain positions.
Valve introduced a new type of ranking system in early August to stimulate and ultimately to deliver a better overall experience to the players.
Now that a couple of weeks have passed, there are players for and against the changes. The main argument against the update is the long waiting queues for certain positions. In fact, there's actually been proof of players waiting over 50 minutes for a game! On the other hand, the vast majority of players have reported a better ranked matchmaking experience than before.

Having said that, it seems like Valve is taking notes of what's happening. That’s why, according to the new update, over the next few weeks, they will be experimenting with a toggling strict solo queue on and off:
Over the next few weeks, we'll be experimenting with toggling strict solo queue on and off, to see the impact it can have on match quality and matchmaking times. The primary reason we initially added this feature was because there was a much larger discrepancy in motivation between players competing for solo MMR and players competing for party MMR, resulting in a poor experience overall. This discrepancy is not as pronounced now as before, and each option that does a hard split of the matchmaking pools has to be considered carefully as it has a direct influence on the matchmaker's ability to find the best matches available.
Whether or not the changes were for the better is still hard to tell. Until then, be sure to report everyone who is not playing his selected role. After all, this is the only way in which we can make our ranked games a better place.
