The Pentagon is available so late in the game that the promotion cost reduction that it grants is almost useless. I think the Pentagon deserves a buff.
If we're fixing the Pentagon, there are other issues that are just as bad, if not worse. Such as Heroic Epic. Ok, build a barracks in all cities. Then, you get a bonus in just one city that encourages you to ignore & sell all those other barracks? So, basically, this is a wide strategy that gives you a tall bonus.
Heroic Epic would make more sense as an Empire wide bonus: its silly that training every unit from one city becomes ideal.
Or, heck, it could be more interesting: Every city with a Barracks is assigned an extra promotion from a list that newly trained units start with.
That way different cities would train different things better, with possible incentive to have Exp buildings in all cities.
Penatagon is useful for
Buy then Upgrade many advanced units can be upgraded without going obsolete (Bombers, Tanks, Artillery, AT gun, Paratrooper)... so it is cheaper (if you don't have Autocracy) to buy the cheap version and then upgrade it.
All very good reasons displayed here, it comes much too late for many players to take advantage of it, I'm sure. I think the only practical reason to build it is to prevent anyone else from grabbing it themselves or if for whatever reason, you're still using Industrial era units that late in the game. Anything else and you're just being stingy or not making enough money. The Professional Army policy from the Honor tree that reduces upgrade costs is much superior in all forms, truly.
With that, I would say that the Pentagon needs an overhaul rather than a buff. Or at least, something to make it not a waste of hammers. Some suggestions:
- +15 unit XP in all cities.
- Great Generals receive +1 bonus range and are 15% more effective.
- All units built in that city receive the unit type specific +1 attack promotion.
- 5 units do not use resources.
- All spies get promoted, diplomats spread propaganda more effectively.
- All cities (or just the city the wonder was built in) act as a citadel. +50% effectiveness of defensive tile improvements (forts, citadels), including the city itself.
- Stealth buff: later unit upgrade costs are scaled up so upgrading from infantry to mech-inf is costly.
Something like this would seem more useful and interesting.
