Fantastic ideas PBI! It's a damn shame the game is so far along in development. If CA haven't implemented your idea by now then I doubt we will see it. If it had been earlier then maybe they might have included it.

The idea of traits for units is something that would add tremendously to the rople playing value of the game. Building up a super-elite unit from humble beginnings across an entire campaign wold be fantastic. Having the name of your unit known and feared across the entire world, having enemies rout just because they came up against them in battle, inspiring your own side to great acts of bravery, all of these are awesome.
