I am expressing my annoyance at this guide being put out last. In my opinion this is the most most complicated normal encounter, with the exception of Madness, and therefor could have been put out a bit earlier. I know you have a lot on your plate, but just saying. That said, great guide.
For 10 man: Depending on your raid composition, you can lust at one of two points. If you have 3 healers then you can lust as soon as Warmaster hits the deck, thereby allowing your ranged to get Gloriana off your backs very quickly. If you are 2 healing it, you need to save lust for the last 20% or so so that the healers can keep up with the tank damage. Either of these strategies works pretty well, and is also of course varied by your DPS caliber and composition as well. As Lore said this is a very ranged favored fight, but melee do just fine.
