I couldn't load up map on my server. But I will play more tomorrow didn't sleep whole night trying to figure it out how to teleport there. A
Anyway I did just a raw preview so you can see Stormwind Harbor... I also bring u up the evidence of ADT map files that are part of orgrimmar raid + some Sha spell that Garrosh gonna cast on Stormwind tho.
Oh one more thing, there is some spell called like this:
147088,"Bombardment","","Bombarding Stormwind! Fires a Kor'kron Iron Star at clustered enemies.","Bombarding Stormwind! Fires a Kor'kron Iron Star at clustered enemies.",0,0,0,0.0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,120994,
Found it on WoWhead tho: http://ptr.wowhead.com/spell=147088/bombardment
Anyway this zone of the orgrimmar raid is called: Transport: Siege of Orgrimmar (Alliance)
There is also Horde one: Transport: Siege of Orgrimmar (Horde)
When I refresh myself Prolly gonna still try to get this from ingame look.
