Having Armor GUI that shows what durability it is at and what your holding would be amazing! because iv broke countless peaces of armor and tools fighting the arena boss mining and fishing ect.

That's annoying but good for the Server though. The more stuff People break, the more Stuff is necessary to be obtained, a.e. do some Villagetrading again, spend some more time interacting with other People on the Server. Just in general, keeps the Market going.
If you'd just need one Armour set, how would it benefit anyone? Nobody would buy anything anymore after the first Time.
Sorry, but it might be great actually, don't know how other Staff thinks about it, that was just my Train of thought.

Even taking into account what jet said about keeping the market going, I still believe this would be a great idea
