Do not forget about X'caliboar, "http://en.wikipedia.org/wiki/Excalibur" refering to King Arthur's blade. Or Spellfire Longsword, "http://en.wikipedia.org/wiki/Lightsaber" referring to the lightsabers in Starwars, or even Merlin's Robe, "http://en.wikipedia.org/wiki/Merlin" referring to the Legendary Merlin's robe. Second Wind/Second Wind, http://www.thefreedictionary.com/second+wind Second Wind: a person's ability to breathe freely during exercise, after having been out of breath, & a new strength or energy to continue something that is an effort. , http://www.goodreads.com/quotes/20028-evil-is-a-point-of-view-we-are-immortal-and refers to Anne Rice's quote “Evil is a point of view. We are immortal. And what we have before us are the rich feasts that conscience cannot appreciate and mortal men cannot know without regret. God kills, and so shall we; indiscriminately He takes the richest and the poorest, and so shall we; for no creatures under God are as we are, none so like Him as ourselves, dark angels not confined to the stinking limits of hell but wandering His earth and all its kingdoms.” (Credit it for me, because I did the research, Thank You.)
I think that Every Day I'm Pand-a-ren is more of a reference to the song "Party Rock" by Lmfao and the line, "Every day I'm shufflin'". I could be wrong, but I know the Pandaren dance is based off that song as well, so. /shrugAwesome list though!
This article is based on achievements, not items/weapons.
I always figured "Ragnar-Os" was a ref to Spaghetti-Os, not Cherrios.
RE : Under "Iron Maiden""Hallowed by thy name" is also the 3rd line of The Lord's Prayer.
Awww. How could you forget 'It's over 9000!"
There is another possible one: The 'Hills like white Elekk' achievement. There is a 2002 short movie called Hills like white elephants featuring Benedict Cumberbatch. However it may be a stretch or from another adaptation of some kind but it might be worth checking in to :).
There is a quest in Jade Forest called "Stay Awhile and Listen" which i'm guessing would be a reference to Dekard Cain from the Diablo series. Also, just a guess, but Kun Lai may very well be named after the mystical city of Kun Lun where the Marvel superhero Iron Fist is from. Not positive, just a thought.
And They Would All Go Down Together (10 player)10/25 man versions are from the chorus of ''Goodnight Saigon'' by Billy Joel (and we would all go down together)
Mighty Roamin' Krasaranger is a reference to the TV series, Might Morphin' Power Rangers.
Just remembered, and other things. How about this: What Does This Button Do?.While I'm sure someone might think it's from something else.I'll remember it from the quote DeDe says in Dextor's Laboratory from Cartoon Network. :)
