That's true.
I miss too many info so to give an advice to buy or not.
I don't know the team-players of @ Desmondd
or his level, competitions he plays and his opponents
or his tokens and packs
or if he can farm and how many per day
or from which country he is
or if he can buy tokens - for example the monthly card costs about 5$.
For some countries it's a just coffee or a beer, for others can be the daily wage.
Also don't know how "thirsty" he is for a title or a treble and how much devotion can give to the game.
Every case is different.
The only thing I can do is to give a more clear view to other managers and explain how the game works
(as the same thing is what I also try to find out).
