There is a default meta enforced by Riot and there is a solution to it
The enforced meta is the champ select system where Riot obligates you to pick any of the 5 roles. At this moment you can only queue up for top, mid, jungle, bot and support. They should add a 6th role called ' miscellaneous' . There you can pick any off meta champ/role and it will be clear for all your teammates that you will not play the conventional way.
