The area is replicated in Siege of Orgrimmar where the raid has to stop Garrosh Hellscream at the end of the World of Warcraft - Mists of Pandaria expansion. If you miss the dungeon because you levelled before LFG was available, you will need to fly into Orgrimmar and be swift about before before the flying guards have a chance to attack you. You might need to have to fly in, get killed then run back, move closer and then die again. If you do that method, it is advisable you run in naked, in your underwear so they aren't damaged so you don't need to repair.
