Unfair matchmaking. In my 10 games 6 of them have afk teammates. you can't have high wr in these kinds of games If you're playing solo. Cause if you're too good they will always give you afk or toxic teammates who have less than 50% winrate. I have 74% wr with 2000+ matches and i just noticed how they always put good players with toxic one if you play on solo, always team up with those players who often afk or have low credit scores. really, this games matchmaking is Tr**h.
