I'm not sure if op is playing dumb or just genially asking a stupid question... But anyways, if you cared to even notice what's going on you'll see that devs have been slowly opening the new lands up to more powerful buildings and structures. So I don't see what's the point in this.
The New Lands are needed now to try and inject some new goals for those that like to actually grow,as a BC i havent even participated in Black Friday and Cyber Monday sales theres no point except to buy allies and further push their price up.Many of my other BC friends feel the same way and its showing up in eb completion times.Having goals to aim for in a game is what drives it,take away those goals and boredom sets in which results in going inactive or just deleting the app in favor of a new one.I'm hoping ATA brings in the new lands soon othetwise the KAW slide will continue.
