If I join a comp match, and 2 people after Agent Selection announce that they are smurfs and they are going to troll the entire game and make us lose because they dont care and they want people to be hardstuck for the memes, what can I do?

You leave,suspended

You FF, denied

You lose, you lose

You report them, nothing happens.

This isn't the first,second or third time that happend. I know the community is toxic, but how come there is no way to deal with this? Am I just supposed to pray before every game that I dont get people who will troll me?

I know IP banning is probably a no go from Riot, but by this point you should find a way to atleast mitigate it.
