"To Kolyarut: I don't get the tentacles comment. If that makes a villain bad, then why do people profess their love for Ulduar? Wasn't that the majority of the Yogg-Saron fight? It was loaded with adds (including parts of Yogg-Saron himself) and even included up to four Keepers helping you out...just like the Aspects in Madness."

That is true, to an extent - though with the old gods themselves the tentacles are the body itself, rather than a disease or parasite that's infested the body. But perhaps I'm not the best person to ask about that, I'm not a big fan of the old gods in general as recurring villains. Ulduar is a special case as it's just loaded with special art and concepts and ultimately a more interesting end-of-world event with Algalon's impending re-origination - even if Yogg is the reason you're there, he's a very minor part of the appeal, IMO.

Though the point about the keepers - we'd just rescued these people from the grip of Yogg-Saron's insanity; they clearly weren't in a position to fight YS themselves. The Dragon Aspects are in a position to fight Deathwing, and do. There barely seems any point us chopping all his limbs off, then beating up his helpless, sad little head.

"In general: I also don't understand why people insist Deathwing should've been much like Arthas. I'd rather not fight the same villain in every expansion pack. That gets boring quick. I much prefer a different story with different villains with different styles."

I absolutely agree that in an ideal world we should have a new, interesting style of villain each expac. Pre-WoW, Deathwing's style was interesting, but in Cata itself he lost it all.
