Trash developers. Closing a tower before it was supposed to and then rewarding everyone with a chance when they people were guaranteed to get a Diamond Card. "We'll give people within 15 battles of completion better compensation." We had at least 45-60 battles to attempt completion, and I spent money on Tower equipment to ensure I'd be able to complete it in time. This is unacceptable service, and I beg that nobody download this app or ever give them your money.
