When on series, make it only give you your primary.
I would rather wait 5 minutes to get a game and play my best possible role when it really counts. Just an idea. It just makes sense to me to be able to play 100% your best role when you are on your series, as it shows your true skill in that role.
Edit 1: I am asking for this, because it would make your series more consistent. Your series should be displaying your true skill, and your primary role is the role you are most skilled in. It just makes sense to have you play in your most skilled position rather than your sub par role.
