I agree, if you can not make progress in the game, just change the game.
Evaluate your time, energy and money spent on the the game, and you see what progress you made in game considering that some people have 4 mil p.atak and 1 mil p.def, and if the progress is to small the game does not worth the time, next game, there is only one life but there are a lots of good games .
I will borrow 2 words from S , the game is made to sink money form rich people.
