It would seem some people have forgotten why tanks exist in the first place. Tanks are there to keep the enemy off of allies so said allies can do their thing without worrying about surviving. DPS can go all-out and Healers can keep the Tanks alive to keep tanking. This trinity will never cease to exist in MMOs so you may as well accept the existance of Tanks. And to those who plan to reply to this statement with the "it's a joke" bit, what if it isn't? What if people really do want Tanks to just become DPS? Tanks need to deal damage to maintain aggro, not just to win, and some people may be forgetting that. Sure I hope I'm wrong and no one actually thinks that way, but still...

That said Dark Knight is traditionally a DPS job, but only because of its tendancy to expend its own HP. If DRK did become a DPS this would end up applied. Do you really want a DPS job that expends its own HP and potentially dies often over it? Or simply makes Healers work more due to it? Furthermore, what would you all suggest be brought in to be a 3rd Tank? And I don't mean switch a DPS like Samurai with it because even in armor Samurai has traditionally been a DPS job too. Also both Paladin and Warrior have traditionally been Tank jobs so they are in the right spot. The trick here is finding jobs to add as Tanks, without using carbon copies (like Knight and how similar it is to Paladin).

All this said, you best believe Dark Knight isn't going to the DPS side. It'd be far too much work to find a replacement for it, let alone convert it to a DPS job.


P.S. For whatever reason it may matter for, Blue Mage and Dancer are the only truly seperate jobs from all available now. Everything else is more or less similar to what we have already. SE may need to invent brand new jobs to keep filling in roles...
