The Jenga Tower at the Ruby Sea

[Okamimaru]

I know I'm late, but good news is that Hell's Lid has become a dungeon in the revived Expert dungeon roulette with patch 4.25 Sadly, Heaven-on-High has not been mentioned in any new content since the initial content with 4.0

Uh heaven on high is the confirmed new deep dungeon... it's on the 4.3 special site along with a new dungeon, new alliance raid, new eureka, new ultimate...
