I'm guessing you haven't played WoW, because each questline has a story to it if you actually read the quest dialog. And we're on a gaming forum so your nerd comment doesn't quite make sense.
Every quest has a story, are you for real?
Every quest is about go kill X and bring me Y. Only since Cata they actually bothered to give more interesting quests and there's even only a few of them like the one in EPL with the caravan. Most quests are still a joke and completely pointless.
And to the guy who said WoW has a good story. Yeah, it sure does, just that you actually don't notice anything. Warcraft has huge potential but they ruined it all with turning it into a joke. No matter how good a story is, you can't expect every single player to be exactly like you, to order every single WoW book, to go read every page on wowwiki. It's up to the developer to make sure people understand the story without having to look everywhere for it.
Everyone who defends "WoW story" is just someone who spends too much time on it. At the end of the day you only need to go outside of any capital city to see all these people who know literally nothing about the story. The only people who really know everything are "achievement [censored]s" who spend their whole life on everything WoW related and I don't consider them the average WoW player.
Also yeah Fallout 3 has a huuuuge world and you can spend your whole life doing random quests but it still has a nice main story line. Just because there are a lot of other quests it doesn't mean that it doesn't have a story. I find it better than most other RPG's who don't have the huge world.
