Dear Khris, you are totally wrong here.
Let me explain my situation. For the last like 10 season all my teams were paired against the same teams. League, cup, CL. Every season, more or less the same teams. Which was totally fine, because the quality of these teams was about equal it was fun to play.
This season I’m still paired with these teams for the cup and CL. However, in the league I see 13 completely new teams. The quality ranges from 70% until 190% (maybe a it was a bit less at the season start). My team is somewhere in the middle. Not a single chance to finish top-3.
Both parts of this story hold for my 3 teams, all at very different levels and from different servers.
I conclude that this new league pairing is the update you wrote about. The pairings get less equal from this update. Not more equal.
If only one of my teams got an unfair draw, I would give you the benefit of the doubt. But with 3 out of 3 I must conclude that this update is a big failure.
