I'll give you a good example of why we don't like this:

I was a solo player queued with a 4-man premade. I had a Leblanc support. You see all of those kills LeBlanc got on Rek'sai, Cho'gath, and Yasuo? And all of those kills Zed got as well? That's because for the first full 11minutes of the game I played bot lane 1v2, cowering under my tower, doing my best to dodge every Morgana Q, and trying to CS. Meanwhile LB and Zed had a field day in mid lane.
I wasn't asked if I wanted to play bot lane solo. I wasn't offered any jungle pressure or roams from mid (until 11min when ZED came bot lane and helped me take the turret because Sivir and Morg went to buy).
Then you know, I was even okay with it. We got up 9k gold at 25 minutes. Their strategy, as boring and unfun a game as it was for me, seemed to be working. Except it didn't. Because they probably pull cheese strategies all of the time and aren't good enough players to actually be in my games. By the end of the game I had the most CS on my team by a large margin DESPITE being at under half of Sivir's farm through laning phase. Zed had 50 less farm than the camped Cho'Gath, and top had 100 less farm than his opponent. The enemy team made the comeback and beat us.
It's bad enough to lose the game, but then go back to what I endured at the start. I didn't queue up as ADC hoping to lane without a support. I queued up hoping for a normal game. And hell, if they'd asked me if LB could start by cheesing rek'sai then getting a couple kills mid, by all means go ahead! I was cool with it as I expected her to come bot at 3min, 4min, 5min? But she kept going back mid over and over again while I got to play the "do my best to get in xp range without getting hit by a morg Q" game. Don't even think of trying to CS.
4-man premades have no respect for that 5th solo queue player. I mean, these 4 people were legitimately cool teammates. There was no harass, they let me take the red buffs late game, they all focused down Cho'gath when he flashed on me in a teamfight to try to save me. They played well and it was mostly okay. Simultaneously though, it's not the game I wanted to play. If they wanted to do a cheese strategy with a second assassin mid to get a snowball going, leave out top or jungle, not ADC and support (as they obviously did, because they know they'll get the support). I mean, I queued Top primary and ADC secondary. If you want to make someone play the lame-game, make that person part of your group. You don't get to assign that on someone else.
I've had quite a few games lately with 2+ man groups. I don't like them as much. Allied or enemies. I think firstly we should know - they know they're going to be camped for, so why shouldn't I get to be told that they're a duo? For allies, I just don't like that my lane gets ignored as they're all going to try to support eachother.
Do I sound salty? Probably. I mean, LB got an S in that game. That set me off a bit - sure she got kills but she didn't do her job at all. She was the support, I played solo ADC the whole game. And yet all 4 of them get their chest for that game because LB got an S from cheesing mid, even though we lost and even though the only reason we were in the game at all was because I played super safe bot and didn't feed kills 1v2 like the enemy mid laner did. (I don't mind not getting a chest as I'd already gotten a dozen S games on Jinx, I was just annoyed that LB of all people got one when she was literally never bot lane for the first 11 minutes of the game...).
