I agree, since that is the version "Deluxe", for being the most expensive, the series BTD5. Relax you guys. Tier 4 upgrades of Specialty Buildings aren't really that special if you exclude the secret ability of the TOTMG. For example, you can't use Splodey Darts in the iOS game when you're not using the Dart Training Facility. Similar examples of premiums that turned into Specialty Building-specific upgrades are Tiny Tornadoes, Double Ranga and Dreadnaught, upgrades that can be used simultaneously in the online and Deluxe versions. I guess the iOS/Android versions had to have their own charm, separate from the PC games.
