All my friends left this "game" because:
1 - there's little relation between what you do and the outcome of games, it's mostly bull-****
2 - after level 10 you take several seasons to sell a player unless he is 150 + 150 + 149,8 and under 29 years' old.
3 - to make it worse they implemented a system where they force your players to accept skill points
4 - from time to time they put you in impossible leagues with token buyer players and you have no chance
5 - it becomes a boring fight between you and budget
6 - you get exactly the same results if you abandon matches
7 - the translations are full of childish mistakes giving an image of lack of professionalism
8 - an overall feeling of being deceived
