I was surpassed where I thought this thread was going. But I have to say it's an interesting idea, Niko...

It wouldn't be any trouble for Nordeus to tweak the "expense curve", by re-pricing tokens, or adjusting the Training Efficiency curve, for example...

I'll keep thinking on this.

I don't know there's a fundamental need to limit. If I stock up green packs for a few seasons, or tanking etc, why shouldn't I be allowed to put them all into 1 single player even if he becomes 9 stars...

It seems like it's solving "around" some bigger problems, like over inflated teams, quality/ level mismatches at some competitions, and an overall lack of trust (at least among some players) of both the system and other managers.
