At the start of this season only, the internal Matchmaking Ratings for all players have been adjusted to push players closer to the normalized average (approximately at Gold 3).
Dude… this was in place awhile ago… and if not this “PUSH” there was another one. They constantly push and pull players… internal re-calibrations. I know you like to sell “git gud”, but to ignore an “mmr push” is ignoring these crazy bad games these last couple of weeks.
