I have around a 2 k.d and I feel this. Most matches are one sided even in freelance it seems that I'm often put with lower skilled players (Apex legends does this to me every match) people can say it's bc we are playing at the same level but there's no way someone with a third of my wins or half my overall kills is keeping pace with me. If I posted my past 100 games from each game it would be mind blowing how unbalanced MM truly is
