Well, the training speed is very high, true.
But this is no reason for paying extra token. We finally have paid for building the academy. We have paid with money, that we earned with the team we have invested token in.

As I suggested in another thread already:
A sort of "registration fee" as new "professional player" for players out of the academy (max. 5 token) would be acceptable.

Anything else is a steal of token!
