Why were you greed rolling on something you desperately want anyway? If you ran as a class that could have needed on that gear, you wouldn't have had any problem. WoD DPS queue is really not bad enough to refuse to DPS it when you want DPS gear.

It is lame when people roll on stuff after fights they did not contribute to, but you had to be aware of the possibly that anyone in the party could have out greeded you at any time...
