Placed too low

Due to the huge rank inflation from last season, Riot nuked the ranks so everyone gets placed much lower instead of slightly lower.

So I won 9 out of my 10 placement games and was placed in silver 3. Is this a joke? Why did I get placed so low?

You got put there because it's where you belong. Try again next year.

You were gold last season, so being placed in silver seems exactly right.
