Allow people to pick 1 role. If they are willing to wait extra time to get that role they want I don't see why not.
Fill should have a "But prefer not" option. Most people have 1 role they just hate and can't play. Using the prefer not option could knock out that role.
Maybe it's just me but I would love to have a class to declare sometimes when we do pick intent instead if a champion. When I get support I would like to show if im going to play a tanky support like Braum or squishy support like Nami.
