I have a suggestion

With the new primary and secondary roles being implemented, many people have quickly found out that if you put support as either role, you are basically guaranteed to get it over your other role. My suggestion is that when queuing up, if a slot is available for your secondary role, the game should skip that slot X amount of times. After X amount of times, you will be placed in the next available slot, whether it be your primary or your secondary role. This would increase the chance for someone to receive their primary role. It is rather annoying to queue up as Mid primary and Support secondary just to get placed as support in less than a second. The game should at least wait a bit to see if you primary role becomes available.

Now, I know many of you may be thinking that this will cause an increase in queue time, which it would. But I personally don't mind a slight increase in queue time if it means that I get my primary role more often. To keep the queue time increase to a minimum, I suggest that the number of times that the game skips an open slot should be kept to a relatively small number.
