Nobody is helping because nobody knows what you are on about.
Of COURSE weapons are going to do more damage per action point as you progress through the game, to account for enemies getting stronger. Why on earth would you think otherwise?
You are basically asking other people to investigate a fairly obvious and fundamental balance issue to do with weapon scaling.
Weapons don't have AP modifiers on them. All one handed weapons seem to cost 3 AP, from my play through. I've never had a melee attack cost less than that, and it can cost more based on skill modifiers or standing further away from a target.
Two handed weapons might have a higher base AP cost to account for their greater damage, I don't know as I haven't played with them much.
Magic items have a variety of modifiers to the vanilla base item. The higher tier magic item (e.g. gold), the more modifiers you can get. I've seen plenty of green weapons that do the same basic damage as a default white version of the weapon, but have some shitty extra like +1 to charm. I've had gold weapons that seem to have higher damage than similar weapons, but not by huge margins. They are potentially excellent because of the amount of modifiers such as 10% chance to blind, bleed, or bonuses to stats. I had an orange/gold axe drop that was +1 to way of the warrior, 15% to mute and 15% to cripple or something like that, so it was pretty nice. But not totally overpowered.
Not sure if that helps to answer your question at all.
