Riot please... let us know when we get in a team with 4 pre mades...
"We gotta go to a party" they said, then all the 4 voted to surrender in a match that was won. That's not cool. It's too much power on the hands of 4 people that want to troll a solo player. Let's not even get into the part where they flame you and all the 4 reports you for no reason...
In the window that ask if you want to accept or decline a match you can simply add a warning saying "This is a 4 man pre made" so we can decide if we accept or not.
