Eh... I didn't find myself jumping in my seat in anticipation with this particular trailer, like I have with others in the past. But none the less, the new Fall of the Lich King stuff is pretty neat, despite the immature community complaining about there being, shockingly, errors during the patching process.
The MMO hardly ruined the lore of the game. It's all there if you take the time to read and do things patiently instead of mindlessly following add-ons to the top. As for raids, they've made them a lot more accessible so that their lore and hard work can be seen by more. However, it's an MMO, and because of that it's a time requirement to do that type of thing. Videos exist if you can't do it. *shrug*
