-A Huge Nuclear Reactor (the building is already in the Worldbuilder but has no powers,so if you want a screenshot ask me ) if you capture it you mustnt build any´Reactors because it produces more Power than you need. ...
... -And I think you should add Units too the Tech-Airfield for America and China because China can build the Helix also in their Airfield so the mustnt capture it, and also America can build the Blackhawk in their Airfield which is I think much better than the Seaking.So the USA should be able to build a Stealth-B2 Bomber which throws Bombs and is really effective and China should be able to build a Transport-Plane which can carry up to 5 Vehicles /or 15Soldiers and drops them as paradrop ,so you can take the Vehicles in the Transporter at the techairfield and let it fly anywhere in the map.
I agree with you on the nuclear reactor one, it just makes sense to have that in a game such as this one.
The Tech Airfield probably will get more aircraft sometime in the near future.
I agree with you that China needs something different and unique at the tech airfield.
The Blackhawks though are not as good as the Sea Devil at the Tech Airfield now. The Sea Devil (ok Sea King) is able to carry vehicles as well as troops. The Blackhawk cant carry any vehicles.
The B-2 bomber should not be part of a tech structure, but as some sort of regular buildable U.S. super airfield would sound right. Perhaps for the U.S. Superweapon and Air Force general.
' ... a Transport-Plane which can carry up to 5 Vehicles /or 15Soldiers and drops them as paradrop...'
I think the paradrop situation is fine as is among the Chinese side. Each side has it's own paradrop specialty. Tank gen can drop tanks, infantry gen can drop infantry, etc...
