plus nin came at a time where alot of multi role players had everything at max level at that time. In this scenario you can level your main through story, get that exp lead then bother with the new jobs as tempting as they are....for career tank and healers, next expac may be a godsend, and who knows how the combat system will change how the roles play out... you gotta admit though a 4th tank or healer would have been really tough to make at this time...
