Either way you enjoy the game or not. If you dont, nothing keeps you from quitting.

Remember; this is a freemium game. you need to spend alot of $ to keep up, thats how EVERY "free" game on the market works. The only desirable change would be a guide on not to spend €/$ before you reach higher level leagues.

I spent around 30-40€ so far, im not regretting it. Every game is about winning and giving you a good feeling about it, nothing more and nothing less. I know ill be quitting this game sooner or later, who cares? Its fun while it lasts. Thats how life goes dude, its fun while it lasts.
