The text file offsets are an absolute disaster to read. I've tried. It would take 10 years to make substantial changes. Even if you did, you would still need the Python source for the next version.
I sent AW a personal message asking for the Python files, but I don't have them yet. With the files, I think I can work through the Python enough to make this work. Or, I could just explain the scale and let someone else do the typing. (The team over at the "Holy War" mod plans to use my model, but they're going to punch it in, and all I have to do is review and test. Makes work for them, but a lot fewer bugs that way.) If you like Python code, I'll send you a complete explanation of the scale, and you can impose it on any mod you like and have the source code for.
Combat is not "more deadly" as such. For the player, who will probably have better armor than the rank-and-file troops, it would actually be less deadly at one-to-one odds. It just requires some tactics. Combat is quicker - you don't have to beat on an unarmored man with a huge sword to kill him. A quick swipe with a good machete will do it. In contrast, higher armor values mean that insignificant weapons (sticks and stones) are less likely to damage armored men.
For example, on a test fight I did in ONR, I took on a number of guys (all with huge swords, but only a couple had substantial armor). First stroke, I cut one of them down. A quick sidestep, and I cut another one down. Third swing got a third one, but at the same time one got me. Not "more deadly" - just fewer total strokes. In another test, I knocked down a couple of unarmored guys with three or four shruiken each, but the one with armor took several hits with little or no damage. I also got a lot of horses cut out from under me ... Japan didn't armor horses. Gives infantry a bit more chance against light cav (but subsequently makes armored horse all the more imposing). It balances very realistically. Stops the "I can take three hits from an axe because I have hit points" mentality.
Chances are, if you had a mithril hauberk, it's highly unlikely that anything smaller than a cave troll could put you out of the fight ... assuming you didn't just stand there and let 12 orcs beat on you. Well, also assuming that, with this hauberk, your head armor was not a baseball cap. "Duh ... my chest armor could stop a ..." THOCK *gets hit in head with a rock*
Anyway, if anybody wants the details for the system, send me a PM and I'll explain them as best I can. (Be sure to tell me what you want them for - I may need to tailor the response for certain situations.)
And if anybody has the Python source for TLD, please send them to me ... or else offer to write up the changes for me. Once written, all we have to do is redistribute the item_kinds1.txt file to let people test it. If it's a hit (which I'm pretty sure it will be - it's been the life of the party everywhere else that has seen or heard of it), and once tweaked, we send the Python source for the next mod version. (If the vote is against it, nothing is lost.)
