Lane Prefs

: This happened a while ago, so Midey, YandereQueenYuno and I were playing a game and something which never happens or lets say which usually happens 1.0% of the time happened. Here look at this picture :) Riot can you please put up a feature where one can select their roles before going in-game or lobby so theres lesser raging and trolls since people rage when they don't get a role they want >.< "Mid or feed" etc... anyway fellow summoners how often does this happen to you? When everything works out? Prefs!! xD
