So we finally set aside some time after our C'Thun kill tonight to learn Ouro. Ultimately it only took us a couple hours to learn him. As I think about the fight and the mechanics involved, I really feel like it's easier than the Twin Emperors. The concepts behind the fight are familiar from our BWL days, and it's actually pretty reminiscent of Broodlord Lashlayer. Take Broodlord, add in a more intricate positioning element, a trivial gimmicky second phase, and a wicked percent based enrage, and you have Ouro more or less. I guess given the difficulty of the encounter it shouldn't feel quite so disappointing when you pop the corpse and only have three drops instead of four like the Twin Emperors.
