Update: well there it is. After reaching town hall lvl 20 the MASSIVE paywall begins. $4.99, $4.99, $24.99. You still have all your content, but the game become a chore. Increasing your heroes lvls becomes nearly impossible, training relys on speedups and you run out of things to do. Oh, and if you don't log on for a certain number of days npcs will slowly kill you. We shouldn't be surprised by this, as EVERY game on mobile is just a pay to win game. Mobile gaming is dead by greed.
