I definitely don't think the problems with premades is universal. There is far more of a likelihood you will have a duo or full solo team than a 3-4 man premade, and most of the time the experience in of itself is 100% RNG as you have no idea what the disposition of your teammates or enemies is when in-game. Sometimes your teammates are golden and make games 100x easier or less painful. Sometimes your enemies tilt themselves and feed. Sometimes you feed on accident and your teammates are trolls. Effectively, that algorithm of SoloQ never changed. As someone who has played a LOT of Normals, against Plats/Diamonds where premades are almost guaranteed every other match, I did not think they were a major issue throughout the season because I was extremely used to them as a Middle Laner and Support.
Well, not until I became primarily a Jungler. First and foremost, Jungling for premades is one of the worst multiplayer experiences I have ever had. I love this game dearly and I think there is no barrier it can't cross, but being the only solo player queue'd into a 3-4 player premade for a Ranked game feels super horrible. Playing against a jungler that has access to voice comms and familiarity with his teammates is often horribly one sided. Meta picks, or pocket picks, it makes no difference - you are already at a tremendous disadvantage purely for picking a role that premades will do better even if they start out poorly.
Furthermore, I have found premades (duos, trios, 4-man groups) to be some of the most immovable and least respectful entities in the game. They want to do a questionable Dragon or Baron? Welp, if you don't go in then they report you afterwards and lose you the game. If you ping "BACK" then they just ignore you. Few things tilt me worse than when I'm performing well as a Jungler in a premade, then the ADC starts making shot calls without having any understanding of why I am not making those calls. You can't argue logic because they claim theirs is superior. Your pings are ignored. If they die or you perform poorly, they flame you until you have to begrudgingly /muteall.
And I know not every has this experience. It's 100% RNG, just like some people have regular Ranked games where no one starts Intentionally Feeding just because their team gave First Blood. I know some people don't have random Anivia supports that steal CS intentionally and don't buy a Sightstone, while flaming your whole team for not giving them middle lane and lacking vision. Twice in a row, back to back games. I know a solid number of players aren't trolled out of their Promos from Silver 1 to Gold 5, but that is my experience every Season I've hit Silver 1. I'm currently Silver IV and am doubting there is even a point to try for Silver 1, even if I fullheartedly believe I can win against Gold-Platinum players consistently.
