Here is what weapon crafters can do:
Artificer – Master Tuning Crystal gives condition damage based on vit and toughness.
Huntsman – Master Maintenance Oil gives precision based on vit and toughness.
Weaponsmith – Superior Sharpening Stone gives power based on vit and toughness.
So how about adding something similar for armor crafting professions that will give a defensive bonus based on you power/ precision.
Something like this:
Armorsmith
- Gain toughness equal to 6% of your power
- Gain toughness equal to 4% of your precision
Leatherworker
- Gain Vitality equal to 6% of your power
- Gain Vitality equal to 4% of your precision
Tailor
- Gain Healing Power equal to 6% of your power
- Gain Healing Power equal to 4% of your precision
