Scale Armor Proficiency seems a bit weak with the stamina reduction being limited to martial stances. I'm not sure how many warriors and rogues are changing stances frequently during combat or wearing scale armor but I think having a general stamina reduction for all skills that use stamina would make it a bit more competitive. 5% stamina reduction across the board maybe?

As I gaze over the horizon, the wind tugs at my cloak and whispers, "Adventure" in my ear.

A squeaky halfling nearby asks, "Why you playing with orcs heads and troll rearends?!"
