Town Points – Is development becoming too formulaic?

I definitely like the current system more than the previous ones. At least because it reduces the role of randomness in the distribution of resources. And the choice hasn't become smaller; on the contrary, the Capitol now requires only a city hall and a city level of 15, and dragons, among all other units, only require Raiders and a city level of 15. And you decide what to build at that level. The Mage Guild doesn't require any level at all; if you have the resources and the hero is leveled up, you can build it to level 5 in the first week.
