Avoiding selected role before searching for a game.

No idea if this has already been talked about, but can we get the option to select roles to avoid? Maybe you are good at everything else EXCEPT top, so you select Fill for the first slot, then select to avoid Top in the second.

How would it look? Have the roles mirror each other, blue at the top like normal, fill in the middle (also blue) but then have the mirrored roles be at the bottom of the select wheel but in red, rather than blue. But you can still only select two things, so it's either fill, two blues, two reds, or a blue and a red, or fill with a red.

In the event that two or more people decide to all have a single role red, have it act as if nobody had it red in the first place, basically behaving like now, only the likelihood of you getting the role you DON'T want will go down, in favour of someone who doesn't mind having it.

Although, thinking about it, doesn't that mean that everyone will get the role they want less, and just get a role they supposedly don't mind doing? I'm not sure, just an idea, thoughts? Also I'm not sure where to put this, in Concepts & creations or in Gameplay... [sg-lux-2]
