Add a feature to pre-set your champion choice to some default one per each role
Similar to how item sets work, you would choose 5 champions (1 per role) which would then become defaults for that role in champion select. This way there are not any "blank" spots where you don't quite know what the player may choose until they actually choose which is too late to ban accordingly.
Ex: say I usually play Jinx as BOT (ADC). I would set it up on my summoner page (outside of matchmaking) so that if I get drafted as BOT, Jinx is already pre-selected as my preferred champion.
