I just returned to play this game after almost 10 years gap and I can honestly say this is not worth a penny spent on it!
I spent quite a lot of money to bring 3 accounts to a decent level buying players and some offers. I started almost halfway to the last season and won almost everything available to win.
New season and surprise surprise, I am playing teams much stronger than mine generally speaking, so what is the point in spending money in this game if my players get nerfed the next season and I am playing stronger teams than mine? You bet I wont do the same mistake in bringing my teams to the level of the ones I am playing!
Also, I can not believe you are asking for 600-800 tokens for a player that next season will be nerfed?
Resuming, I am not gonna spend any more money in this game!
