My 'worry' is not so much will a DRK tank be a good one or not, is how long it will tank a new DRK tank to be able to hold aggro, as a consideration towards how geared will a DRK tank be at the start of it's progression. I.e. will the Dark Knight have gear at the start to be able to tank a darn thing, or will it be going through the usual gear progression, that prevents said such from being able to hold aggro, in a party with the same overgeared older Jobs, that makes for tanking 'heck' (at least,) for PLD and WAR tanks, undergeared as they are, as a fresh 50 tank is.

If a new 50 DRK tank 'has' the gear at the start, to hold aggro, that a fresh 50 PLD/WAR doesn't, at roll start, then said PLD/WAR types should complain at the devs, a tad bit. (Even if we all can play the same Jobs, regardless.) As such, I expect just because a DRK tank can start at 50, doesn't mean they will have the gear to tank properly. No Staples 'that's easy' button there, for DRK tanks, I suspect.
