I want to put forward a general question here:

Do you guys realise that the people who play in pre-mades aren't purely people who want to stomp teams and get easy wins? Casual players are very likely to play in pre-mades because they don't like PvP and only play with friends. Your solution would force casual players or new players being introduced into PvP by a friend to get stomped repeatedly by these pre-mades that you say are a problem, causing them to quit PvP, losing us new players.

So it's fine as long as you don't have to see the pre-mades, right?
