Since when did this game become DUO or expect to lose?

I mean I just had two players in my game with 49% overall winrate with one having 700 games and they were playing a new champion in ranked... To my surprise they lost lane. Oh wait, it wasn't a surprise.

The second player was top, 125 games on riven 49% winrate on her 149 games overall 49% winrate... guess what. Also lost lane.

Had a shyvanna didn't gank once, but if you died she was there to farm lane.

Support did well.

Every time I died it was 2v4 at best because shyvanna wanted to split push, but got out split by a banner of command.
