Im Cruious, where Do you think (When we get there) The raid where deathwing Is an Encounter will be located? We've pretty much Cleared out Deepholme of Twilight's hammer, Cleared out Grim Batol, and cleared out The beastion of twilight (To my knowledge, feel free to correct me)
So.
Where's a giant, worldbreaking dragon left to hide? (For that matter, where is Deathwing between now and his raid??)
