Well, I have to say I'm very disappointed, because I will never pay for tokens, that I have to pay 28 tokens for my youth players I have waited 21 days for!
Not being funny, but if you upgrade the stadium, you wait 30 days, which is annoying, but its an achievement when it finishes. Its yours, and you've paid the penalty of not spending tokens to make it faster by waiting.
So, with the youth players, I have paid the penalty for not paying to speed them up, so why the hell should I have to pay 28 tokens for my player! I've waited 21 days, he's mine!!
Nordeus wont care, as they will make a fortune out of the Ambromich/Sheik Mansoor token buyers.
But for casual players, the youth players should be free - it also adds long term playability.
