"Items used in combat should not last forever."
I picked up a really nice Viking Sword of the Vampire that had splintering weapon 20%. It literally went from 160 Durability to 3/160 in three swings, the last swing being a splintering hit. Garbage in less then 20 seconds. And it didn't even come close to killing the Stone Golem I hit with it. As is, I had to re-equip another weapon to finish it off.
Although it was a nice 3 swings, at this rate of weapon destruction, there is no point in even picking the thing up, let alone wielding. Not good for much other then melting it down for the relic fragment.
Even if it WAS repairable, 20 seconds of swing time does not a useful weapon make....Last Forever? An hour would be nice.
