Matchmaking improvement

After playing LOL for some times, I do like to play a specific role. Presently there are 5 differents roles 1) Top, 2) Mid, 3) Jungler, 4) ADC, 6) Support.

Prior to get a matchmaking, people should be able to select the position they would like to play in the team. The matchemaking will match players accordly for not having 2 or more players playing the same position.

In championship, all players have their position. It will be nice to play the same way in a solo queue.

Thanks !
