If you don’t know which buildings are important and which aren’t, then you probably play exclusively against low-level AI or at an Elo where this doesn’t matter.
This doesn’t relate to gameplay but rather to the setting of the game.
I know that, but time changes, and when we use this as a serious argument (which it isn’t), then the devs can clearly forget about adding anything slightly new. More importantly, you recently made a post regarding a buff for the militia line (If I could have only one buff for infantry). Using that logic, I could simply say that “Tracking” shouldn’t have been made free since it has been in the game since 1999, and I don’t understand why the devs made that decision with the Definitive Edition. Or, specifically regarding your post, I could simply say that this isn’t a good idea because the game is over 20 years old now and no new stuff should be added.
