I do not think most raiders would like that. MMOs tend to be a very "I gots that and you do not" kind of pride thing for people sometimes. You know how it goes.
You already have badge gear you can get if you are unlucky. True, it is not as good as some of the drops. But still.
That said, I kind of wish there was a random drop system for random BGs/ rated BGs like the raiders have.
