From your experience what order of the rank is from least to most toxic?

Gold Silver Bronze Diamond Plat

Challenger/Master Gold Silver Diamond Bronze Platinum

Gold,silver,bronze,and per lvl 30.

Plat is the most toxic.... I just have to be honest... Masters Gold Diamond Silver Plat 5-3 For some reason i get games where people say i am high ELO IDC lol its stupid

I have to say, with experience between silver and gold. That gold is much more pleasurable to play in because the player base there is generally pretty happy where they are at for the most part. They get their rewards and encounter few trolls.
