Hoplitai and 0.2 density

[Zett]

But they a Romani, they don't use shield wall. They are very disciplined and have a good training. And i think their formation is not so close like a shield wall.

About the barbarian units that Phalanx300 posted:

I could give all units with javelines that should also fought in a denser formation a 0.3 density:

Dugunthiz (Germanic Spearmen) - 0.3
Herunautoz (Germanic Swordsmen) - 0,3
Dugunthiz Hattisku (Chatti Spearmen) - 0.3

units that only fought with swords a 0.3 or 0.25 density:

Thegnoz Drugule (Germanic Heavy Infantry) - 0.25
Druhtiz Herusku (Cherusci Swordsmen) - 0.3

and for the others:

Gaizoz Frije (Germanic Levy Spearmen) - 0.3
Gaizoz Alje (Celto-Germanic Spearmen) - 0.4 (standart, cause they are levys and throw javelines AFAIK)
Druhtiz Skandzisku (Scandinavian Spearmen) - 0.23 or 0.25
Druhtiz Habukisku (Chauci Spearmen) - 0.23 or 0.25
Herthaganautoz (Germanic Bodyguard Infantry) 0.4 (even if they are elites, they carry smaler shields, fight with sword (secondary) and the unit descritpion says nothing about dense formation or shield wall

Noricene Gaecori - 0.3 (javelines)
Milnaht - 0.25 or 0.3 (swords)
Arjos - 0.2 or 0.23 (im not sure, I would prefer 0.23)
