But... there you have one problem: Nordeus is a money-grubbing company. If they change it to a fair competition for "everyone", they lost lot of their asian "friends" (attention: cliche), who sell every end of the season their players and buy a new full squad (mostly fast trainers) - I have one of these (surpisingly a chinese guy) on my server: last season he spends 100 Token for ONE Fast Trainer. This season, I saw him two times biding on Fast Trainer, one for 69 and another one for 54 Tokens... After buying those guys, he trained it to 7*, instantly...
And that's a really big problem... money is all you need, to win (nearly) everything.
My suggestion is now: Why don't make the cup like Associations? Only Stars matters. So you can't exploit the system and the asian guys will keep buying (maybe more restpacks than FT). Maybe they will even more, because they will need up to 8*-Teams to overrule everyone.

I also think, keeping your squad like a real team will also be more interesting.
