So it's my understanding that mithril armors are just like regular armors, they still offer the same protection. Except they're lighter.
The way it works in game is that a mithril armors get +2 MDB -3 ACP and -10% ASF and count as an armor type lower, as in a fullplate counts as a medium armor for proficiency purposes. Breastplate counts as light allowing evasion to work and so on and so forth.
My problem with mithril armors, is that they only offer the prr/mrr of a lighter armor. This pretty much makes mithril (something that should be awesome) turn into something that should be avoided in the current meta.
So I guess my question is: Is this intentional or an oversight?
