Town Points – Is development becoming too formulaic?

Why just one? You develop however you want:)

Well, I haven't played it, so I can't offer any constructive arguments.
Perhaps my understanding, formed from reading some posts, is fundamentally incorrect. And I won't argue until I play it.
But for now, my opinion hasn't changed, because I haven't seen any development paths in the fifth game, even according to other people. Therefore, I will continue to consider the introduction of these points as a reduction.
