Namely that the other missions don't lead to artifacts or connect to artifact missions, so all the player needs to do is complete the artifact missions.
See, the problem with the story isn't the mission separation. It's the separation of the storylines that connect the missions.
Take BioWare games, for example. The way they handle subquests and main quests is clever. In order to keep the main quest well-paced, you have to keep coming back to it. You have to keep progressing with it. Therefore, when you get dropped in a new area, you're quickly told what your main quest objectives are. However, if you visit the local town (or whatever) and talk to people, you'll get a number of side quests.
The resolution of most of these side quests requires going into one or more dungeons. The same dungeons that completing the main quests requires you to go in. In short, the side quests do not inhibit the progression of the main quest; you happen to be in the neighborhood on business, so you do them.
By segregating side quests from the main quests, such that progression in a side quest doesn't help your main quest progression at all, you lose pacing. You don't talk about the main quest much anymore; it drops into the background.
You can imagine that the original 10-mission version of WoL was basically the artifact missions and maybe one or two of the sidequest missions. Maybe some of the Horner ones and one or two from Hanson and Tosh. Perhaps there were only 4 artifacts instead of 5. Whatever.
When they expanded it, they expanded it wrong in terms of story. They didn't want to change their story, so instead they just made larger, more involved side-stories. That's not the way to tell a bigger story; that just tells a wider, more diffuse one. The side quests needed to be involved in the main quest to greater degrees.
