I think that was the perfect remedy to this auto-fill bullshit, but it was bad because it made the wait timers longer... But is that really a good enough reason?
We can't always get what we want and everything has a cost. For example; The cost for faster times is auto-fill and the cost for getting the role you want every-time is longer wait times... To me, the latter solves more of the bigger problems. Is that not reasonable? I'm pretty sure a lot of people are willing to wait however long it takes if it means getting the roles they want. Frankly, nobody wants to be stuck in a 30 minute game doing something they don't like and get flamed for it. Overall, it even considers the people who hate waiting because all they have to do is hit fill.
