You're making things far too complicated.
Think. Under the current auction system every single token and every single dollar spent by the winning bidder to buy a player goes to Nordeus.
Why would Nordeus want to reprogram the whole system if not to recover even more of the tokens and cash we have in our accounts?
I know you've suggested a sellers fee, but when Nordeus is the only seller on auction............that's all. They get everything.
Someone call the monopolies commission.
