About the price, 24 tokens are much, but at certain players (good performers, multiple position players) it can make sense in higher levels (top of server). In lower levels normally the regular transfer markets offers better deals and the youth acdemies only use is IMHO offering some income by the 2* player that can be sold (due to the 2* quality I made good experiences to build the academy in level 3 in order to find customers for the youngsters).
