Who called what position first - Possible fix?

@Riot When playing a Normal game, I can't tell you how many games have gone wrong because of auto lockers. People fighting and arguing over who called what lane first.

So I was thinking, why not just create buttons for each of the possible positions? Whoever clicks on it first gets it, as it becomes grayed out for other players.

It would more or less likely force other players to try new roles as well as new champions. Also, I believe auto locking wouldn't exsist as much except in the sense that they arent caring about team synergizing.

Just food for thought. ~ Negative or positive, I would like to hear about other people's opinions.
