Odd that I haven't seen a thread on this (and I did search, didn't see anything), but ... Army of the Dead ghouls do not taunt Murozond.
As far as I know, he is the only 5-player boss (at least that I've seen) who is not taunted by it, which is usually reserved for raid bosses.
Evidence that elements of the scrapped War of the Ancients raid were utilized for the Hour of Twilight heroics ?
I mean ... the Hourglass mechanic really is one of the coolest mechanics I've seen in any boss encounter, 5-player or raid. Not to mention the gorgeous scenery in Well of Eternity. WoE is even more detailed that Grim Batol, which iirc was originally intended to be a raid zone.
Thoughts ?
