Trade all Jade Hare Ornaments (which no longer have moonlight boxes to open) for Weapon Fragments. Replace all Jade hare drops and rewards with Weapon Fragments rewards.
Its really a poor trade but personally I'd be less frustrated every time i got a jade hare from Levers of Fortune, or saw my unclaimed mission rewards etc...
For example, I've got about 70 jade hares in my stash, that puts me close to a level 60 purple sword I guess, definitely not as good as opening 60 moonlight boxes, but it would at least eliminate the frustration of the worthless items.
Side note: maybe replace platinum boxes with 2 weapon frags???
10*gift vouchers would also be acceptable
