I am pretty sure some Slavic Macedonians have been playing with Macedonians for some time. 

Yeah, it's everything but ideal. But English just doesn't have the word needed.

If there is a Gemanic tribe called Germans already in the game, it should have been called Cimbri. But it was left as Germans.

In AoE you have. Short sword. Broad Sword. Long Sword  Legion/Legionary

It's normal, many RTS don't have progression. Sometimes people don't feel the technological improvements.   Age of Empires 2 isn't a good example. In AoE, there are eras, while in 0AD, there aren't any; you don't go from the Bronze Age to the Iron Age. That's fine for ages, in 0AD there are no ages, the equipment of a centurion is not much improved compared to that of a princeps. I recommend you see it more like Total War series logic. Again, this isn't about turning 0AD into Age of Empires, Delenda Est did a better job with scouts.  Putting centurions instead of a princeps makes no sense. It's like evolving from a corporal to a lieutenant.  In Age of Empires, it goes from upgrading a 18th century militia to a 21st century marine.That's the logic of AoE. If you want real changes, it's better to differentiate the equipment.

Let me split a hair here: While some Germans are already playing it, the game will have Germanic tribes, right? (OMG, what a bean counter I am!)
