I felt the same way as mavis when decay was properly implemented. You have to adapt. The mechanics of the game are such, that, you have a wide variety of things you can do and many ways to do them. If one doesn't work because something changes, then you just have to implement a new strategy. It's hard to think clearly when "the devs ruined my game," but when you step back, sleep on it, and think about what you CAN do instead of what you can't, I think you'll find new paths to prosperity.
