I'm very disapointed that every 'evil' character from the warcraft series suddenly becomes a killable object in the World of Warcraft. Having to deal with Illidan and Archimonde(although they did wrap up the Archimonde-story pretty well cause of the Caverns of Time) to get my Tier 6 armor was a big turn off for me, I'd rather see some new boss turn up which we can kill than having to kill those major characters over and over again.
Adding Arthas/the Lich King to this list was another great disapointment, but I will get the expansion anyway as the new Death Knight hero class intrigues me, just as the new Inscription-system does + an increased level cap.
Heh I never had any interest in the lore of WoW, I read it but hell... WoW feels like one big grind to me, quests aren't badly written but they have nothing of real consequence.
I feel like Blizzard just slaps everything of Lore they got around gameplay elements like how toddlers colour drawings, because they like the colour purple more and not because it makes sense to colour gras green... "We should do new dungeons... The Lich king is cool, let's use him".
Anyway, I just read quest objectives in WoW, doesn't really why I do them lorewise, cus I know when I'm 70, or 80... I'll kill the real badasses 2 times a day.
That's one of the things where WAR seems to attract my attention, questing doesn't seem merely a mechanic to level. But from what I hear, weather I play PvP or PvE its actually has some effect on the world.
But it all remains to be seen, first let a couple of hundred thousend ppl play it before I'll give it a chance.
