Disclaimer : I intend to play a Bard, so may be biased.
You will have 4 instruments + 2 weapons at mid game and above.
At least 2 out of 4 top line instruments are droppable and the class mechanic is built around using them to enhance your buffs.
If the option to have equipped gear not lootable is chosen, I would suggest Inventory slots be not lootable as well as to take this into account (ie trade off between bags and safe pieces of gear seems fair).
<=== Eagerly waiting for it to start
