Job flavors or lack thereof

Was browzing the boards the other night and read a post about job specializations (the coffee hasn't hit and for the life of me i can't think of the right word) from the standpoint of lore/themes. Got me wondering what every thinks of or what could be improved upon in relation to how the jobs come across from a thematic standpoint or roleplaying perspective. I for one always miss my pet wyvern that drgs got in ff11. It was less of an active pet and more of a passive boost but ill be damned if i didnt try to keep Rigor up and running, he was my bestest boy. Personally I think the occasional job specific quest every once in a while would be a great addition. Thoughts?
