In this way, certain buildings become more valuable and players will be forced to protect them even more, adopting the strategy of destroying them themselves to prevent their enemy from capturing them.

There were civs in ancient time that like Mongols , who kidnapped engineers to build siege engines.

I had an idea that you might like: If you capture an enemy militar building, you can recruit units of that civilization as mercenary units paying with metal and you can recruit only mitilar units that your faction don´t have as mercenaries. For example, if you are using Spartans faction and you capture a iberian barrack from your enemy, you can recruit iberian swordmen from that barrack for maybe... 100 metal. . If you capture a enemy workshop from Romans, then you can recruit a balista as mercenary units for maybe... 300 metal.

Good News, I have a gaming PC now. I bought an Radeon RX 550 2gb, I´m very happy right now!

The Germanic tribes is a spearman faction, it should have a elite spearman unit.

That´s what I thought!

I´ve always liked Battle for Middle Earth style! But that game had a problem, when you choose several squads they move mixed.

@real_tabasco_sauce 1. "units don´t actually fight in the formation" wrong, if you put your troops in front the enemy´s units they will fight while maintaining formation. 2. The battle formation exist to be an advantage in battle, no one chooses battle formation for cosmetic but for win. 3. Bonuses are not rare in this game, for example range bonus: ir you build a tower in high ground, it´ll have more range. I don´t see how complicated the solution I´m proposing is.

Well, that´s the point of add battle formation bonuses. You will have an advantage in the game if you use it.

An interestic point of 0 A.D is the battle formation of most of the faction in the game: Phalanx for Greeks, Testudo for Romans, etc. But, does not exist are battle formation bonuses, wich is a drawback because it´s necesary. Melee units die very quickly againts ranged units, witch make very hard to invade enemy city and forces the player to use specific units like cavalry, rendering melee units useless. The necesary solution is implement battle formation bonuses for each faction in the game, add defence bonus againts melee attack to Phalanx and testudo formation, and add defence bonus againts ranged attack with a shield wall formation. Here an example of Celt shield wall formation:
