I don't think that is actually his point. This is supposed to be a MMO hybrid. Even if there were 100 additional story missions you would still have to do the raid multiple times to acquire a full set of gear. That is actually an intentional design choice on the part of the developers, and has nothing to do with the amount of content. I will point out that even though you mention the same bounties as a negative you don't seem to think that additional bounties are a positive. Not to mention that Eris today just unveiled a new "mission" with one of her quests. We honestly have no idea how much content she is going to be able to dish out over the next 2 months.
