Feng in MV bonus rolled his agility ring, twice, to bads its unquie equipped. Keeping the other one atm for lols.
Bonus rolls are a great thing except for blizzard did not think about adding in a system if you already have the item, you should not be able to bonus roll it again. Getting muiltiple items like this is a punch in the face. Im always "Woot, finnaly won a bonus roll..........crap. I got that already!" Thanks for getting my hopes up.
