Ouro = teh Smashie

[Mirajj]

How would you rate the difficulty and learning curve of the fight, say compared to the Twin Emps?

I'd say that Ouro is easier than the Emps only in that he's more 'forgiving'. Emps has to be 15-ish minutes of no "big" mistakes, and very few "small" ones. Ouro has several different strats and things you can do. Once you figure out the best way for your group, and pull it all together...he's not so hard. Having a dedicated crew helps, too. The Emps took us 6 weeks of 'work' to solve, due to a highly rotating roster. One raid was even cancelled because of lack of bodies. But with Ouro, we've had 3 solid weeks of pretty much the same folks on him, and took him to the cleaners.

because Ouro is particularly difficult, or because no one else has seriously tried yet (devoting their time to C'thun and Naxxramas).

Few folks are interested in "optional" bosses. Why bother when you can go right for the big guy, right? As well, Ouro used to be VERY hard. So folks have passed him by. It's the same thing with Vicidious. There is no "need" to kill him, and he's certainly not a walk in the park boss...so why bother with the effort of spending weeks to learn a boss you don't 'need' to kill anyhow.

This is even more so true with the carrot of Naxx. "Why should we bother with this optional boss when there are bigger fish out there!?"

Our Council decides that before we'd do any serious attempts on C'Thun, we'd put Ouro into the ground. That has, I'd like to think, driven our raiders to great heights in putting the big worm down, as everyone is eager to kill C'Thun!
