Do you think it would help if Nordeus would make the bracket of possible levels a bit tighter? In a way that no matter how much you dropped your quality, you would never meet managers more than two levels below you? So in my case, the level 25 manager would at minimum always have to deal with level 23 managers.

That would also reward a more long term perspective when you build a team, adding a spot of realism to the business of managing your team. I mean, which world class club sells half of it's staff, fills up with players from the 3rd league, and then sells those and goes on a shopping spree on the world market?
