Great post Stuff :)
As a note - at lower levels you won't be able to get 100% repair and, because of this, some items you will not be able to repair - namely ones that have a total durability of 1 (1/1 for example). I have noticed a few of the 'starter' items have 1 durability, so repairing them doesn't work.
I know that is probably a 'duh' for some of y'all, but it kind of confused me the first time I played when I tried repairing an item only to see nothing happen. I then took the time to read the skill description carefully and looked closer at the item that was broken.
