Sacrificial Pit – how to use it correctly?

I disagree; the Horde definitely has a worse economy. Based on my city development and strategy, I always have enough money, but I wouldn't mind increasing the growth rate. The Tower has a small population, so even +1 Fury makes a noticeable difference....

Well, just because you have a certain city development strategy doesn't mean everyone else does. Personally, I wouldn't refuse extra gold and always send newly joined neutrals into slavery. If you manage your economy well, you can even manage to build Assassins by the second week, and build a Stronghold early, which means you can also build a Castle. But this requires taking gold from chests and sacrificing 5-7 thousand. As for the +1 Fury... Well, in a month, you'll have 4 more Furies than you would have otherwise. Of course, you could make the bonus bigger, but that would be more complicated. Plus, you have to build it specifically, while the Orcish Pit is a necessary part of their development, which isn't ideal, but it ensures that you won't have creatures without a place to summon them. And... only the Tower has a Pit. The others have different names
