Old news is old.

Seeing as the new jobs are introduced in the expansion and new areas that you can only get to by doing the story, yes they are "gated" if you want to call it that. The story is pretty darn easy to complete though, in fact the only difficult/semi-difficult story trials to complete were just recently added in 2.5 and 2.55. Everything else that is required for the story is a breeze.

It may be a bit time consuming but this game's story IS the reason why the new areas even open up to Adventurers (ie. us player-characters) and it doesn't make sense as to why Ishgard would be open unless you've completed the story to the point where the Gates of Judgement would be opened for us as they have remained shut the entire time beforehand.

I see no problem here. These new jobs are not jobs you can start out as, they are unlocked via story completion and purchase of the expansion. There is no problem here. Story is essential in a Final Fantasy game. Don't like it? Play something else then. *shrug*
