NTBF – New buildings for the towns in Tribes of the East 3.1.

Are you still considering building suggestions? They aren't exactly brilliant, maybe a three or four out of ten. Here's what I've got.
First idea: A building for the Dark Elves that increases the growth rate of Hydras and Minotaurs, and also allows you to sell units for gold. It could be called something simple like "Black Market" or "Slave Traders' Guild." In my opinion, it wouldn't break the balance too much, because you can't increase the growth rate significantly on the sacrificial pit, unless you're willing to sacrifice your own units. And that large ruby provides the ability to see the element of creatures (I don't remember the name), which doesn't have a significant impact on magic damage.
Second idea: A Foundry. It allows you to increase the growth rate of Golems by using Goblins, as if they are working there. It also increases the attack, defense, and health of chests, tents, catapults, and the Golems themselves. If necessary, we can adjust these bonuses, or we can replace all these increases with an ability: it fires magical arrows, the damage of which depends on the hero's spellcasting skill, and is calculated indirectly using a formula. Of course, balance isn't a concern here.
In my opinion, this would be a great counter to the Dwarves' tower, and it would give them a significant advantage.
