Also, given the fact that you start at lv 1, they could actually use this as an opportunity to introduce jobs that wouldn't work in the current PVE environment. I recall them commenting how if they were to introduce a job like Blue Mage, they wouldn't want to take away what make sit special, it's ability to have a wide range of monster skills to pull from.

So with Deep Dungeon, this definitely does look like the best opportunity to introduce new jobs that are only accessible within said dungeon experience.
