One of my friends can now use a average low 3 star quality team to lead a league.
The average quality is 70.3. At level 13, it just reaches 3 star.
The team has many 4 star (appearing as 2 star in eyes of my L15 team) players with SA, but does not have even one 5 star player.
He has a comfortable lead in league. I checked some teams in same league. Their qualities are similar.
Constructing an average 3 star team by the end of the season is now an alternative to take over a 2 or 3 level lower team. If the manager is active and buy some 5 star player after league draw, their team quality will be easily higher than most others'. At the same time, their team may also enjoy to participate a easier cup. This may be a easy way to collect titles. I am considering even though I wonder if I will have fun to play in this way.
