To everyone out there complaining. All I have to say is "are you a dev?" Do you work for ATA? No you aren't. They run a business. Yes it is a game, but it is also a business. They have to do what is right for their business to keep growing. If you started playing the game today, and saw how much money you had to spend in order to get to what your stats are now, would you honestly keep playing? Hell no you wouldn't!!! You would say that is ridiculous and quit playing. They have to have a balance to attract new players. As for the drop in prices for T4 that everyone is so pissed about, quit whining!!!! Just look at it as a lot of hard work you did. Feel proud about the time and effort you put in to get where you are. No new players will be able to say they worked as hard as you or I did. Take some pride in hard work instead of being pissed someone might get something for less!!!! If you are that upset about the new release, just quit playing!! No one makes you play the game! Live with the decisions the devs make or quit the game!!! No one want to hear you constantly whining!
And by the way! Look at all the buildings that are from T1 to T4. They are basically the same. A defense attack build, a balanced attack build, and a build that is focused on attack. So if you like the build you currently have, say with circles, I'm pretty sure you will be able to buy the T5 balanced stat building and still like the build. The buildings have always followed those rules. Three different attack buildings, a spy building, defense tower and spy defense tower. Look at your build now, then tell yourself "I will have to same build with T5, just with higher stats!"
