Dark Knight

[Shurrikhan]

If anything it looks like a heavier, more "do your best" and take hits in the face, passive mitigation tank (or at most evasive mitigation through spells/seals) than anything physically nimble... Its heavy armor and likely enlarged health pool seems to make it ideal as a dual-option heavy dps / tank that, when in the dps role, can easily swap into off-tanking and can use increased vitality for larger nukes (though at cost of consistent dps compared to going full strength)... I don't exactly have faith in the team's ability to make something interesting of a self-sacrificial mechanic in a tank either, though I think it's possible in other hands. Of course, just as much as none of this is perfectly set in stone yet, I really doubt we have a voice in the matter.

:: just a side-note, from what little we have here, the impression I get is that of a 2h Frost tank, back when that was a thing. Huge armor, decent enough health, acclimating and sapping defense, good parry and magic defense, and a bit of burst mitigation/absorption through spells.
