I hate playing with 3-4 man pre mades

This new champ select has made it nightmare for solo players when they get paired with 3 or 4 man pre mades. Me and some other solo players I've talked to have ran into the problem of being completely trolled by the pre made they got paired with. We've had the champ we wanted to play banned and the role we were assigned taken. Now once you are in the game and everything is under way you better make sure you don't do anything to upset the pre made. If you do something they don't like then get ready for 3 or 4 people typing in all chat to report you for being toxic and for calling them names. What are you going to do? It's one voice against three or four. I feel really sorry the people unlucky enough to get put with a trolling 3-4 man pre made in ranked.
