After the comedy video, here comes some more serious stuff.
DPS check is tight, not because of the enrage, but because after the 5minute mark it becomes pretty much unhealable. That being said I didn't even have Army up at the pull and didn't use a 2nd potion so it's not exactly super mega tight either.
Cooldown management is pretty much the key to soloing this fight.
Another important part is about using Heroic Will, even without being afflicted by Fading Light, in order to become immune to Unstability damage when it would kill me otherwise.
