Armor Set hotkeys

Analogous to Weapons sets.
Sometimes I want to change my armour during a quest - occasionally in the midst of a battle.
e.g. I keep 2 sets of arm-wraps one set with a Sup attribute rune and another one with a Minor attribute rune of the same type. Sometimes it's nice to swap them if my health is dangerously low. An Armor Set key would help a great deal.
Also, as a monk - I have Judge's armor for heavy melee and a set of saintly armour against elementalists - it would be nice to be able to swap them on the fly.

There are so few people who need this, and so few people who can actually afford more than one set, that it isn't really worth it.

Not everyone uses the Weapon Set option either - It'd just be nice to have that option for those of us that do - even if the default setting is "unassigned."

This is less practical than being able to swap skills on the fly. Armor changing in the midle of a fight would not be instantaneous - nor would it be able to be done without leaving you vulnerable.

If anything, there should be more more penalty to it than there already is...

Since I'm a monk I'm in the background most of the time so it's not unreasonable to swap armor for me. A warrior would probably have less utility for it.

But I agree that skill swaps would be nice too.
