The Dark Knight, as most have said, seems to be a jack of all trades. it doesn't have the DPS of the warrior or the mitigation of the paladin. it could be argued, if an individual had all three at 60 - with equivalent gear - there's be no real reason to take a Dark Knight in any situation.

If this is the case, would it be so hard to accept DRK being changed from a tank to a DPS entirely? What I mean is, reworking the class so it has no emnity skills and is simply a melee DPS like in FFXI.

Otherwise, I can't really see a niche for the DRK or a way to rework it, as many have suggested, to make it a viable choice.
