Plus, most of those missions are soloable. So I think I'll probably get it at some point in the future (six months after release or so) when the early bugs have been fixed, and just play through all the story content.
I'm curious as to how much story content there actually is. Bioware claims that they have a unique campaign for each class but how long are those campaigns and how well-crafted are the missions? If it turns out that each campaign is only 10 hours and comprised of generic MMO grind quests, I'll pass. If it turns out that TOR has awesome 20-hour campaigns for each class, I'll probably give the game a try for a month or two once the initial game price goes down.
Early video stated that there's more content in a given class'es campaign than any single BioWare game.
