TL;DRPutting armor on the Quickbar and selecting it should equip the armor.
What ?Selecting an armor piece that's been added to the Quickbar currently picks the armor up onto the mouse pointer. You then have to carefully move the mouse pointer over to the correct slot in the interface and drop it there to equip it.
Worse, selecting an armor piece on the Quickbar when you already have that armor equipped... unequips the armor, throwing any items in the extra inventory slots across the ground.
It would be much more intuitive and make much more sense if armor selected from the Quickbar were immediately equipped by the character. If it was already equipped when the armor was selected, nothing happens. (Don't un-equip it, please!)
Why ?I am trying, but can think of no use case for Armor being placed on the Quickbar other than for it to be equipped.
Having multiple armor sets (i.e., equipment grids) for different task uses and being able to quickly switch between those pieces of armor by selecting them on the Quickbar just seems right. Logical.
Especially since the Quickbar already designates different slots for different instances of armor in the player's inventory, and even darkens them out if the specific selected armor piece is not currently available in the inventory.
Thank you for any consideration.
