Sorry mate but i think you play this game really bad.

ask some consultation about economy because this games is all about. And now its really balanced now all buildings have they purpose. It was fun that ppl build cannon chain only for making quest or titanium chain now its all useful. And this PW stuff as fishlich mention for running out resourse i hope they make something for gc cuz now this game have really to much of it... So dont blame game blame your bad knowledge about this game. You just playing worst scenario in this game.
Sorry if i offended you but just cant read anymore when ppl cant calculate and blame system not them self.
