Forcing us to the entire story quest to unlock the new classes is just bad business

We can argue the means all we want. This was a set-in-stone design decision by the developers and venting about it won't do anything substantial.

Point of the matter is, Astrologian, Machinist, and Dark Knight all require fairly considerable investments in other classes for cross class skills to begin with. So there is advantage in gating content to them that requires a person to take another class to 50 first, as the player saves time on one of these required sub-classes.

There is nothing set in stone in the world of mmo game design.
Other than grinding to 50 and completing the msq because the devs say so there is no reason what so ever to take another class to 50. There is no cross class dependency or any real lore.
Do I support the idea of having level 50 character before you are given basically a "hero class" yes I do. But the completion of the msq (which is already bloated with fluff and filler) is imo unneeded.
