I've integrated some of the suggestions on this board, made some additions, tried to eliminate all the errors that might have crept in, and re-typed the descriptions ofr all the units whose names I changed. Unfortunately, if you rename "Archer" to "Heavy Archer" because it carries a plate cuirass, that deletes the description, which is a pain=) Also, I upped the stats for Soulless... because in my experience, they are harder to get than longdead, yet vastly inferior in every way.
Longbows became armor-piercing (and dropped to 8 damage), mauls became armor-piercing (and dropped to 5), barbarians got berserk 1 (with morale 9, they are unlikely to berserk, though), barbarian leaders get standards so there is a reason to use to lead barbarians rather than normal commanders, villains and pirates get pillage bonus (and villains get better stats), all Jotun units get limited cold protection (25% for wolves and vaetti), bottom-line militia (for the most part) get their cost dropped to 3, xbow range is reduced to 32 from 35 (in RL XBows fire straight rather than in an arc, and have shorter range than even shortbows), jaguars and Cu Sidhe get new attacks that are better than before, Wolf Herders are made cheaper to reflect how weak wolves are, Ctissian predator lizards are made cheaper to reflect their value, assassins get throwing knives, all satyrs get 2 natural protection rather than 1 (goat hide is tougher than leather), soulless that should have natural protection (jotuns, atlantians) now have it (previously only ctis soulless got it), upper-end archers get 11 precision, and many many other changes. I can't list them all here, but I CAN post the completed portion of the mod

If you spot any errors, please say so!
