Nate, you are entitled to your opinion but could you cite some reasons based on the numbers I have presented, or your own.
Well, I gave my reasons in the original post, but let me post in a different way:
Light Armor
- gains zero benefit from the "counts as lighter armor"
- is proportionally more difficult to saturate the dex maximum
- little benefit from half physical weight (already pretty light)
- Requires least amount of physical material
- Requires least amount of time and skill to craft
Medium Armor
- gains highest benefit of "counts as lighter armor" (removes movement penalty)
- similar difficulty in saturating dex maximum (only slightly easier)
- more benefit from half physical weight
- Requires slightly more physical material
- requires slightly more time and skill to craft
Heavy Armor
- Large benefit for some classes by counting as medium armor (barbarians, others who don't know heavy armor)
- Easiest to saturate dex maximum (+2 or 3 is pretty achievable)
- Highest combined maximum armor bonus and dex bonus in game
- Highest benefit from 1/2 weight loss
- highest volume of physical material needed
- highest amount of time and skill to craft
A fighter, cleric, paladin, or other heavy armor wearer is generally going to have a 12 dex when he starts, maybe 13 if he wants dodge feats. In order to "fill out" mithral full plate, he only has to spend 16,000gp on gloves of dex.
If the above-mentioned character wanted to try to fill out a mithral chain shirt, it wouldn't even be possible without inherent bonuses and/or stat increases.
Even a dex-based character who starts with 16 dex needs a +4 dex item to fill out a mithral chain shirt, and that assumes he's 8th+ and puts stat increases in dex at 4th and 8th. That same character could put on regular-old fullplate +1 for much less money without the stat increases and get the exact same total bonus to AC.
So.... that's why I think it makes perfect sense for mithral to be more expensive for heavier armors.
