Siege of Boralus: Lady Ashvane's Return

*snap*

And that's the sound of narrative flow being completely broken.

Putting the end of this entire questline behind a Mythic only dungeon was a dumb idea.

The Balance of Power quest chain was fine being Mythic only because it was something extra and there wasn't any sense of urgency in the narrative.

But this? No. The attack is suppose to be imminent, but oh they'll wait for the player to gear up first. *sigh*

Siege of Boralus was a Mythic only dungeon prior to 8.1 and couldn't be queued for via LFD/LFG.

Post patch 8.1 Siege of Boralus can now be run on Heroic difficulty and is available from the group finder.

The entrance (for Alliance players) is under the Tradewinds Market.

Alliance will need to complete the Jaina storyline up to this quest (available after completing all 3 Kul'Tiran zone storylines) to unlock this dungeon.
Horde will need 7,500 reputation into Honored with the Honorbound faction to unlock this dungeon.

To skip the dungeon. I abandon the quest and take it again from Katherine Proudmoore at Proudmoore Keep. After taking the quest, immediately talk again to Katherine Proudmoore and choose to skip the dungeon (the first option)
