Discovered something interesting in a guild group in Firelands just now.
I rolled Need on a BoE trash-drop, which became soulbound (as intended) with the usual "can trade to group member within 2 hours.."
However, when I traded the soulbound item to another group member, it turned back into BoE! Tried with another and same happened
In short:
Trading a soulbound item won from Needing in 'Need before Greed' (A usual pug) causes it to turn back into a BoE which can be auctioned etc.
Enjoy it while it lasts!
