Also, according to the wowhead page for Reins of the Blue Drake, it does NOT drop from Malygos but is only available from Satchel of Exotic Mysteries for level 85 players.
It's been changed back. I believe the actual page may look inaccurate, similar to the droprates on Mimiron/Invincible, because of sudden changes.Comments from 4.0.3 notes:Reins of the Blue DrakeThis mount will once again be available from defeating 10-player Malygos without needing to use the Dungeon Finder. The Reins of the Azure Drake will only be available on 25-player Malygos.
I absolutely love this guide, it's very helpful... but it may need to be updated to include the new Worgen mounts.
Maybe time to upgrade the Information, Huh almost been two months of Mop and nothing new..
It would be awesome if this guide could be updated for 5.1 :DI do check back thru my list of guides often & this has been one of my favorites :D
