Many of the changes look interesting but something must also change in the league.
Seeds is the only way!
My team is now 118% but this month I am in a league in which there are 10 teams among 123% and 130% (almost the same range -20% at the beginning of the season).
I have to fight till the last match to stay in the first 8 position while some of my friends at the same level can easily win their league with a 90-95% team.
This is not fair! And with the new rules will have impact also in FA because I will have only 2x multiplier.

Another suggestion... in seeds do not consider the mean value of the top 14 players but the highest % of the initial formation in an official match of the season, to avoid sell and buy trick.
