Change Autofill Protection to Guaranteed Primary Role

The current system is flawed. Too many players are forced not to pick support as their secondary role despite liking it a lot, simply because they do not want to support all the goddamn time.

I am one of these people. I queue as MID/ADC as opposed to MID/Support because otherwise, I would just end up supporting all the time. It can get exhausting.

Pretty sure more people would queue as support if it guarantees a primary role for at least one game afterwards. This way, players could play each role for half the time instead of getting shoved to support 9 times out of 10.
