There is a real lack of more "authentic"-style midevil-based armour, especially surcoats, hauberks, etc. I know that I've been struggling with this for my own mod that I've been building... I've even become so frustrated that I've been looking at tutorials and trying to figure out if I can do the graphics myself. I know there are those out there with much better skills...
Specifically, my mod is based very loosly on midevil England... so I would love to have tunics/surcoat with a lion, griffon (both in the standard heraldic traditions)... but most importantly, a simple cross (knight templars, hospilitars and teutonic knights all used the cross as a base for heraldry).
