Personally I expected it to be a tanking class and I am not at all disappointed in being right about it. I am hoping it will have regenerative abilities (minor not major so not to off balance current healing classes too much) alongside health sacrifice to benefit either itself or the party in some way plus few nice enemy debuff skills alongside high HP and amour, some epic amazing looking 2H weapons too. If had all that I would be extremely happy with it but even if does not meet all those criteria, a DRK being a tank class is the first time I actually desired to play as a tanking class and I doubt I am alone in that so SE made a smart move with this despite some people just making assumptions about what role will play prior to being announced for FF14 and turning out incorrect.
