Before the herp a derps show up saying that visual rank isn’t equal to MMR, lets me assure you the only one of the silvers wasn’t well vetted for their rank (<50 games). Most were well over 150 games.
But this perfectly illustrates league toxicity. If you isolate the top G2 vs S3, everything went down exactly as you would expect, along with the expected toxicity. The jungle G4 vs S4? Everything went down exactly as you would expect, along with the expected toxicity. One team having the best 2, possibly 3 best players in the game, while the other team has the obvious worst outlier? Everything went down exactly as you would expect, along with the expected toxicity.
I understand that perfectly balanced games isn’t really going to be a thing, but we really should get better results than what is shown here. The only way this game wasn’t going to be toxic was by herculean self restraint by the players.
It’s also worth eliminating the variable of possible duos. Inspecting the players doesn’t indicate a duo on either side, the best I could tell all 10 were solo players.
Generally toxicity is a manifestation of frustration. Even if you’re not participating you’re often witness to it unless you full mute everyone all the time.
