how to make the game fun for solo players again?

we all know it. in most games as a solo player you have premades in your team and on the enemy team.

the premade jungler will ignore you most of the time and anything that goes wrong is always your fault even if you are objectively much better than than his premade. they won't ping you anything because they are on teamspeak.

if your opponent is part of a premade couple, they will stick together and 2v1 you every time. dive you every time, roam into your jungle together after warding it up and kill you 2v1. this can happen to solo players on both teams, so it evens out. the only thing it accomplishes is to make the solo players want to delete his account because this happens on a regular basis and feels like your teammates were actually your opponents and you're playing 1v9.
