i told you my maths , with example fast trainer will be 1.5 level (by level i mean 5 quality points higher) than a normal 24 player for 3 season sure and the next 4 propably 1 level higher , that cost generaly 56 tokens (if you are lucky and buy 1 for 10 tokens)

vs

a 7 season 24 player (buy and sell each season) that will be 1.5 level lower and max 21 tokens , and what do you mean by longer you will keep a 18 year for 10 seasons till theit 28 ?

and not calculating the use of red packs cause they are kinda too random to take into consideration
