You gotta hand it to the dev team for convincing an entire generation of players of the necessity of troop cards then squeezing the supply and jacking the prices. Sure, it comes at the cost of an apparently permanent cap of 155 troops that we can build for free, and they didn't even bother going through the motions of adding a new pathetically underpowered troop to the factory and barracks in Space Age, but whatcha gonna do, right? Hell, Big Pharma should be taking notes from you guys.
If this were a case of them finally realizing the damage troop cards have done to the game after 2.5 years that would be one thing, but I see the multi-tier sales and offers for crowns or cash continue at their usual frantic pace.
