remnant from when they only had bronze/silver/gold, and shortly after plat, where due to the Elo distribution at the time, they didn't want to disrupt it too much, as they added more tiers it got slightly better, but they never did a huge shift like this to try and balance it out. Huge changes, feels good to see.
I like most of the changes Riot is doing recently but they really need to get a grip on smurfs and ofc toxicity in ranked... This is the first season ever where I just played my 10 placement matches and was just done.
