i think free tokens system right now is fair enough. if u login daily, u get a total of 35 token. not including win tokens, negoisations etc. with 35 token u can get 3-4 5* players with the right tactic and timing
even if u get so much token, u cant spend it freely because lack of money
so be smart, buy what u really needs, cos for me, its fair enough with free tokens system right now
but, ur idea not so bad either
