I don't even like playing with premades, when the 4 players on teamspeak just carry the match and ignore the rest of us.
The free win for my weekly is nice but you can't get any medals because the game is over so fast. The best you can do is just sit back and fight a few 1on1s to, entertain yourself while they face-roll the competition.
I don't think they should be 100% seperate, but the queue should emphasize premade vs premade and PUG vs PUG. Because pug v pug always end up being the best matches (had a 2% to 0% denova game last night, it was glorious!)
I agree, pug vrs pug is some of the best matches i have ever played in, pugs and premades need their own seperate que and a cross server pvp que to boot.
