I don't so much care if they replace the jobs, so much as they need to simply... feel different. One melee class honestly feels the same as the next, what the original dev team failed to achieve with the current class system, is diversity in play style.

Whether they re-do the current classes, add new, or completely replace those in the game now... I'm fine either way, I'd just like there to be some significant difference in how each one plays.
