The previous (random) system was ok.
My good mix is 4-5 active good teams, 4-5 medium teams (but able to do "damage" in some games) and 4-5 low q teams but not abandoned. Those teams with 33 y.o. players, playing in random positions, crippling players, giving domination in some teams or just a typical 3-0 to others must stay in the fridge or in a league strictly with those teams.
I don't understand (or don't want to be to suspicious) why they change the league system.
The complains about the league was very few while all the managers are complaining about the Cup draw.
