So, is that a dagger? (In the new concept art.)

I am lmao at all the people saying it's a mage outfit. It's like nobody watched the 2.2 trailer or something. That is clearly a male cat DRG.

Keep your eye on the lower right corner of the video. A DRG can be clearly seen popping out shoryuken while clad in a frilly skirt + pants getup.

As for the weapon, it looks very much like the business end of the Gae Bolg Zenith being held pointed down and at an odd angle making it appear short to the viewer. DRGs do this all the time (before and after a jump). And DRG has attacks in which the lance is held with 1 hand, though this particular DRG does not appear to be in the middle of an attack, it is for dramatic effect.

There is already a DRG in the art work and SE don't usually have duplicate jobs when they show off parties, in game or artwork.

I don't think it's far fetched that a new job would be included with 2.2. YoshiP himself said that jobs would be included outside of paid expansions so everyone could try them out.
Also it's been 6/7months since release so you'd think the battle/ job team would be up to something.
