its not write in non place you most or not have trainee of different or same ages, are choices.... its a managerial game and you most do choices, not be forced to do things in one way
whatever different age, different level and you will never get the point to play with your trainee same time at same high level, in a game so take 10 season for complete a trainee at high level it should be the minimum to have 3/4 seasons to get results of your loooong training, using them at same time in the right place... at least i guess users deserve the chance to can do it
you choose to buy over 34 and try sell them double priced after drops because you may find a chicken, others maybe like and wanna make different choices, its a game where people are free to make choices, i just hope to can make more without change dramatically the game
