Sadly, this prevents people from doing "out of box" picking, since the other 3/4 players would simply kick the player if the player chooses to pick something unconventional.

The ranked requirements are fine, the problem lies in the fact that you lose rating/league points because someone else is trolling. Simple stat tracking could detect if a person is trolling/feeding intentionally. If that is the case, simply make the other players lose less rating and the person trolling / feeding lose a lot more. This is obviously not a flawless concept, but this is just a comment post :)
