so OW uses bell curve ranking....
and it actually works. you still get the top peak in their "diamond - grand master rankings" and it still represents the best players in the game. the top still has that competition and everyone wants to go higher. while simultaneously it makes the ladder actually geared towards ranking up without the trashy "I cant rank up at all anymore, I lose more LP than I gain despite winning 50% of the time, why am i falling?" - that only exists for the top 1%, everyone else can still climb.
in overwatch you could win only 45% of matches, but you could still climb rank due to the fact that they have addition systems to measure skill outside of wins/losses
"bell curve"
vs
"log scaling"
the majority of players find themselves in the middle of the ranking system as opposed to everyone at the bottom. everyone is free to climb and rather quickly at that. no longer do you have to play X amount of games minimum to rank up.
come on riot, lets get it done.
