Being at level 10 for both manager and club, I have seen this happening already in my last three leagues but usually it is only a few teams so it doesn't affect much. It seems like there are usally only 5-6 teams that actually care to contend for the title while the rest seem have given up on the first match. I feel this is in part due to disparity in club quality, although I do understand it is hard for Nordeus to put all equal teams in each league considering all kinds of tricks managers play to give themselves an edge. Quite often a -10% team will hardly put up a fight it seems.
