Well, if you look at the gasaetae's status, you will see that his armour is something around 5 or 6, i don't remember very well, and 3 defense of shield. All that these guys got of armour is a helmet, would be nice to decrease theyr armour to 2 or 3, or make them vulnerable to missile atack, specially for the reason of realism. And i agree with the 11 or 12 of defense skill, because these guys were realy awesome fighters.
