MMR Floors and division drops.
I don’t know if it’s truly possible to match make for “skill” because party composition plays such a huge role in success or failure.
Some party comps dominate. Others do not. It’s luck of the draw with me.
Oh, sure, get good and learn how to beat a dominating party composition. Easier said than done when there is a reason they are dominating. “Overwhelming, overpowering” damage.
Not implying it’s fair or unfair or balanced or unbalanced, just stating what I experience.
