I am sick of any pre made (2-4), not just 3s or 4s
I think even the old system was flawed, even having a duo on a team is putting the enemy team at such a disadvantage. Take for instance, a duo Qs and goes for jungle and top, or jungle and mid, that mid or top lane is now going to be camped hardcore. A ranked ladder, should not accept more than one person going in and getting Qd with 4 other random players. That is why 3v3 tree line, and 5v5s were created, solo Q, actual solo q, is the true king of what this game is.
