The Rogue who could

Link. Be sure to read the YT description/commentary.

After being historically inadequate for soloing purposes (e.g. the first Onyxia kill was accomplished considerably later than most other classes/specs, in May 2009), it would seem that the tides have turned.

He says in his commentary that no Twins explanation is necessary; I find it very conspicuous that he could pull one of the twins at a time. That should not happen, and after watching the pull a few times in HD, I can't see him doing anything out of the ordinary to cause only one to aggro.

No intention to poop the party. I think what this guy does is pretty neat.

Its an acomplishment for sure, but I have difficulty calling them truely 'legitimate' kills when you have to exploit factors outside the normal fight to win (stuff that if they were current progression content would likely have resulted in GM intervention). That said, Kudos for the ingenuity used in figuring out ways to accomplish these kills.

I suspect that the tuning of Ouro and C'thun at release would have made fighting both at the same time suicidal anyways, so I doubt there'd need to be GM intervention on that. Single-pulling emperors, though, don't know how it's possible, and I'm certain that would be fixed (or branded as an exploit).

I'm sure that any class could use the Ouro+C'Thun trick (which only applies to soloing anyway, so I don't think it could be called an exploit), but single pulling one of Twins? Yeah, that's not legit.
