I don't understand the fascination with duplicating items. I never read how to duplicate items the regular way, but by setting my repair hammer to a hotkey, the game accidentally duplicated several of my items as I repaired them. I found it to be very annoying. I have no less than 5 Umbra swords. I have many duplicates of quest-specific weapons and armor.
Sure, I can sell the extra crap, but it's not like the game withholds money from you. You can find items to sell in dungeons and caves for great prices and boost your mercantile skill at the same time. I don't understand why so many are crying about the fix for item duplication.
I'm glad Bethesda are getting off their collective asses to fix problems that should not have made it in the final game. $60 is too fucking much to pay for a beta version. At least, the FFXI beta was free with a copy of February's OXM.
