What class will need to do a Dark knight

What class will need to do a Dark knight FFXIV Gil and others classes ? you guy maybe put it on website too.

No. Obviously you'd need those for cross-class skills, depending on if both will be from the other two tanks, FFXIV gil but you only need to have any class to 30. (I hear this often and it's pointless if that's confirmed, as you need to have completed the level 50 storyline to go to Ishgard and pick up the new jobs)
Either way, you just go to Ishgard and pick them up if you're able to.
 Its a stand alone job... You'll be able to cross class skills but don't have to have another tank to get it.
