Any team promoted will face in the higher league teams stronger than it, since the teams there are playing in the higher league for longer time. Doesn't any league system works like that?

Also, your statement has one fatal flaw: you pretend to be promoted on top 3 each season at all cost. That's not the case, or we wouldn't play by this sistem. You can park the bus or try go at it, but the point is nothing should be changed.

Or else, buy tokens and scouts and compete for the top.
