The faction who really needs some sort of buff would be the sweboz..like even one armor upgrade for a select group of units. I get that's how they're supposed to look at game start, but by late game close to C.E? Do they really have the largest roster of infantry pretending to be "heavy" yet at most wearing really comfy tunics and shirts? The best helmets available are super outdated round bronze bowls? Man, the Germans back then were really, really brave (and insane). The Celts have those naked dudes, but the rest of their elite roster are all heavily armed and armored in the latest mail...
