Riot should create team gameplay mode

Whenever (This is normal blind pick) I play a game, 50% of the time I am teamed up with 5 solo people on my side and team people on the other side playing together, or team on my side and 5 solo players on the other side. This creates an unbalanced team when one side has a lot of synergy when the other doesn't.

Riot should create a solo play mode for normals where only solo people are chosen into the gameplay so it becomes fair. Same goes for team play mode.
