I had not looked at the stats. I do agree it could be reworked to not be as strong, maybe closer to a Roman siege wall? And Gaul walls could have stronger stats (or be improved with murus gallicus technology).

I see, but Borremose was "fortified by a moat and an earthen wall", but let's be generous and say earth=stone. Anyway, what seems fishy is that their HP is 1000 to 3000, almost like for the Athenians at 1100 to 3300, while for the Gauls, more known for their stone walls, it's 800 to 2400, although they seem to build them faster. I think earthen walls should be built faster than stone walls (no need to shape big blocks and lift them), but be weaker since they can't be so tall ("HP" is hard to evaluate but the game doesn't allow wall capture, which should be their actual weakness).

Some suggestions for German unit names: Rammabagmaz is supposed to be ''ram beam'', but if rammaz meant ram it might just mean the animal and not siege engines in this timeframe (Ram as a siege engine might just be a translation of Latin Aries). https://en.wiktionary.org/wiki/Reconstruction:Proto-Germanic/rammaz Maybe battering ram could be called Bagmawaldōz (beam wielders) Mangārī is a later Proto-West Germanic word, trade ship could be called Kaupinizbaitaz (merchant's boat) or Saiwikaupô (sea merchant). Note that the word kaupô is a loanword from Latin and might not yet exist in the game's timeline (but so far i could not find any native proto-germanic terms for merchant).   Hero specific names:   Seeress' specific name is a later Norse word. Could be replaced by haljōrūnō.      

Well currently theyre just bigger wooden walls that hold troops, not really stone walls. The Germans seem to at least have built fortifications in their own homeland before migrating, whatever the walls could be manned i'm not sure. https://en.wikipedia.org/wiki/Borremose (A fortified village found in a region of Denmark sometimes theorized to be the Cimbrian homeland. It was abandoned in the 2nd century.)

I think these, along with Walls, should be removed, like with the Spartans, who actually did end building them in the middle of the Hellenistic period.
