I Will Genuinely Do Anything To Have An Option To Avoid Teaming With Premades
The vast majority of toxic experiences I have in this game are with premades (duos in rank or 2 or more people in other gamemodes).
If it's ranked, they refuse to surrender games to the point of holding games hostage, are quicker to flame cause they have a second person to flame with them as back up, and will troll and harass more often than those not in a premade because again, they have backup. In fun game modes they are even worse because they completely disregard those not in their premade to the point of nearly trolling them for the sake of their premades fun only and are even quicker to turn toxic and start harassing people than in ranked oddly.
There are very few positive experiences with premades (not zero just very few), and the more people in a premade the worse it tends to be. I would literally give up every skin I've ever purchased or have gotten to have an option never to have to queue with a premade. You'd think being in a group would make you try harder and be better as you have the communication and all that, but most of the time they perform far worse and try much less hard over all and it's frustrating.
Toxic premades are up their with smurfs as one of the most frustrating parts of this game that riot doesn't care to fix for some reason.
