The Corrupted Ashbringer has never been available on BMAH, your bluffing.
I am keeping an eye on the BMAH on around 40 servers with level one's I summoned there, and I have NEVER seen any other naxxramas loot on there except for the actual tier 3 pieces, nor have I never heard of the corrupted ashbringer being on BMAH before.
