Yeah. And Warcraft's dragons are like every dragon out there. Warcraft's undead are like every undead out there. Warcraft's demons are like every demons out there. Warcraft's dwarves are like every other dwarves out there. Warcraft's elves are like every other elves out there. Warcraft's trolls are like every other dwarves out there. TES http://tvtropes.org/pmwiki/pmwiki.php/Main/OurDragonsAreDifferent http://tvtropes.org/pmwiki/pmwiki.php/Main/OurOrcsAreDifferent from this. It's not like, "okay, this World of Warcraft has gnomes, I see. I remember that in Dragonlance gnomes are silly little guys who make crazy inventions that blow up all the time. Oh, they're the same here too." In TES, it's more like "okay, there are wood elves, I bet they live in harmony with nature and are friends with birds and all that tree-hugging hippy stuff... Oops, wait, apparently they're crazy cannibalistic shapechangers and they only eat meat, even their booze is made from meat. Ugh."
In the end, the minutia and trivia such as "what is the name of the orcs' homeland?" or "how old is the empire?" is not interesting lore, it's fluff. It's still important to know that fluff when you're making the game or attempting to create a lore-correct mod, but it's not something that leaves a real impression. Warcraft orcs come from Draenor, they could have come from Z'baraklar it wouldn't have changed anything. The Septim Empire is 433-year-old in Oblivion, it could be 276-year-old without changing anything.
What matters more is the concepts and the visuals involved. Which is partly why people in this part of the forums were disappointed by Oblivion, which looked too generic fantasy, saying that this was the death of lore. Morrowind was shock-full of strange concepts and exotic visuals. Oblivion has standard fantasy fare. And Warcraft is 100% standard fantasy fare.
Warcraft has a lot of in depth lore actually. It's just, you can't simply find it by running around in WoW raiding dungeons. Even the campaigns in the RTS series do not cover everything. Much like the TES Lore forum, there is a Lore forum on the blizzard websites. People discuss about the 6 (?) or something wars, the trolls fought. Which tribe exactly the playables belong to, which tribe they descendet from and wether or not the nightelves are troll's ancestors or the other way around. It's endless stuff you can discuss on. As I was only truly interested in the nightelve's lore (I liked Tyrande way too much and screamed IRL when I met the high priestess in Mount Hyjal), it is the only lore part I can comment on with actually giving advice. The NE's lore is tight pretty strong to the distruction of the Well of Eternity and thus to the story of the Aspects and their betrayer deathwing (Onyxia is one of his daugther's, boy is that dragon mad. Sheogorath could learn something from him). Our heroes: Illidan, Tyrande, Furion, Broxigar and Kadgar (? think it's not spelled correctly) all show up in that epic first battle against the burning legion (btw those warcraft demons use a lot of "machines", not very usual-demon-like, if you ask me). You can learn, why the Blue Dragon swarm almost vanished, who freed Alexstraza and stuff like that. Or, where did all the demi-gods go ? Not to forget, NE didn't have druids before that, it was only then, Malfurion learned to walk the emerald dream (another sphere which is ruled by one of the 5 aspects).
Did you know Lady Vashj was actually one of Azshara's handmaidens ? She betrayed her queen like 4 times now in several ways and I wouldn't rely too much on her, if I was Illidan, but oh well, we killed them all. Pretty sad that is. (Azshara is still alive as far as I know, though.)
As for the bloodelve drama:
The High elves were actually nightelves that fled from Kalimdor after the first war against the burning legion. They had to go, because pretty much all of them were "Highborne" who pacted with their "new god": Sargeras.
As we learn in Reign of Chaos, The Scourge corrupts the Highelves fountain, Kel'Thalas gets destroyed. The one's who survived suffer from an ill madness caused by a lack of magic, because the source of power ain't there anymore. (The NE who stayed in Kalimdor were mostly commoners and learned to use magic w/o the power of the well of eternity as a gift from Elune (with help from one of the oldest red dragons who wasn't old at that time). Except for Illidan (who did all that he did, only because he wanted to be a noble, but got not accepted in their ranks) the nightelves could only use magic at night during that time. Illidan however managed to evolve some skills, so he could use magic everytime he wanted to. He's easily the most powerful mage among the nightelves until he meets Sargeras.
It is announced their change is not complete yet. We do NOT manage to kill Kael'thas Sunstrider (one of his ancestors was actually the captain of queen Azsharas guards) and he will return much more changed. The blood elves you can play on Horde side are "run-aways". They are trying to overcome the hunger for magic.
Since my boyfriend was a Horde-lore freak it had to learn quite a lot about the orc's lore aswell. And not everybody is happy about Thrall (even keeping his name) and his "peace" with the humans. He's grown up as a human and only learned much later that he was not only an orc but also the abandoned last child of the frostwolf tribes leader's. You happen to learn even things like, orcs babies get milk with their mother's blood and stuff like that.
If one is a bit into all that lore, you can discover a lot of lore related quests and items in WoW. If you however, never read a book about it or are not interested at all, it will appear like your flat god-vs-evil-average MMO, tho.
[...] could go on like that forever. While the lore is every different and not "high fantasy" it's still rich lore, in my humble opinion.
Excuse my bad English, it's not my native language, but I hope, it's understandable. =P
