Leagueofgraphs has pretty good graphs showing where most of the player base is. (Mostly scattered through lower silver) the median of players is silver 2 ish.
Skill wise no one is really good until d3 where there is only .30% of players.
I'm d5 and I see that I'm not even all that great. I just know how to play the game (i dont have great mechanics however).
Most aren't that good mechanically or 'skill wise.
But that pretty much anything I life. Either way the best way to climb out of silver is to actually have people stay in lane and push... And mute.
No one has anything important to say in silver and I see how many people lose cause they can't get objectives and games last yoo long...
You know there is a problem when people pick or ban vayne/yi most games.
