1 - Getting new young players the last day of the season is annoying... and if you get 1-star and 3-star players (thats what I got recently), they are absolutely useless the next day (1st day of new season)... We all should get young players at the beginning of new season, not at the end...
2 - 7 teams promotion is silly, 'cause if you don't get Champions League money bonus at higher level, you are stuck with much weaker team than heavy token buyers... all you can achieve is to get promoted as 5-7 placed team over and over again...
3 - Some of special abilities are useless... Playmaker doesn't create more chances than when playing without that SA... Penalty kick specialist is also useless (my penalty kicker missed 5 times in row)...
4 - Rest all timer is moving forward all the time... it should be always fixed to the same hours (3, 6, 9, 12, etc)... it's annoying when you realize the timer moved from 5 minutes before the game to 5 minutes inside the game...
5 - Homegrown players should get performance and training bonuses while still in the home club, and those bonuses should disappear once the player is sold to other teams...
