Op.gg is so incredibly inaccurate with MMR
2 days ago the league average MMR of s5 was 1020, and i was sitting at 900 mmr being told im in danger of being demoted.
16 wins, 2 losses later my mmr is 1121, but now the s5 league average is 1250 and it tells me im in danger of being demoted.
this is why its stupid to trust op.gg or lolking for anything other than your recent statistics.
