I thought it was a problem that some items DO stack... Like rings, it's dreadfully annoying when you try to switch rings, and then have to re-order your inventory to get it back to the way it was...
There should be a jewelery specifically for buying rings and inscribing on rings. So no one crys, inscriptions can be removed, and the ring 'reset' for a charge. That way rings won't stack, and we'd all get a new craze

'That is Ring of War of Middle Finger'.
