With some focus the quests could probably be done in a few days. I guess they could add a character booster feature for people who want to experience the game's raiding or pvp as soon as they start without doing any questing or leveling, but on the other hand people who would skip content probably don't have much commitment to the game and wouldn't remain subscribers anyway. Raids are important but this game has much more casual content than it does raids. To love this game you really have to enjoy the whole questing and story experience.
