Dynamic Queue Primary vs Secondary
I think that for the first game of the day Dynamic Queue should prioritize your primary selection almost to the exclusion of your secondary. After that it could go back to however it normally calculates efficiency. If on your first game of they day you get to play what you want then getting mixed results after that doesn't feel so bad. But when your start off with your not so preferred role then it starts to feel like "I never get to play my main role". So if your first game of the day set the right mood then I feel there would be less frustration overall.
