Please change item repair such that it can be done without changing classes. There is very little value right now in "self-repair" due to the time necessary to switch classes, then go to the armoury inventory, find the item in question, and repair.
The mechanism when you click repair on an item should simply check "Do you have a level X armorsmith? yes? then repair.
This could also come in handy (even in a minor way) to repair gear while in an instance. I don't see why this can't be done. Right now, we can't because the game mechanics forbid job switching while in an instance. I get that and that makes sense. But, allow for item repair without changing to the appropriate class.
Re-establish value to repair.
