Power Buildings

In my opinion, Behemoths are unique in their cost compared to other creatures with the same growth: Behemoth-2750, other level 5 units - 4000. (Exceptions: Champions, Thunderbirds, Black Dragons). It turns out I'm getting a solid monster at a uniquely low price! Although birds are even cheaper! But when building the enclosure, only 1 bird is added compared to 1 behemoth! Of course, Nobility will restore justice (+2 behemoths or +3 thunderbirds), but it's not worth the effort because such a horde of monsters will be difficult to hire if you consider the growth increase for other units as well, and the Treasurer with Mining won't help much! And leaving monsters behind is not good! Remember what you do when you first capture a nature Castle from the computer: you buy out the creatures from the portal and turn them into castle guards!
