Take the training wheels off ranked team matches
When play ranked with faker you should see bjorkerson and wildturtle on the other team. End of story. This punishes high ranked players, its lonely at the top and getting there costs friendships, deal with it. Maybe we can have an easy/hard button but honestly if you want to smurf you should have picked normals anyways.
If bronze V queues up with diamond 1 the opponents should be diamond 1 in ranked and somewhere inbetween in normals. Yes this does prevent a type of unranked practicing for after you've been boosted, boohoo play some customs.
edit
also you should be forced to take the full 5 into ranked after handpicked recruiting similar to teambuilder
