As someone who played XI, I was unhappy with 14's DRK at first and how they made it into a tank even though I loved tanking in 14, but when I gave it a fair shot I found I loved it more as a tank and really enjoyed it. In the end, it doesn't matter what our perception is, the devs have intended 14 DRK to be a tank and it will always be that way, so they gave RPR for the "DPS DRK" fans which was really cool.

The most iconic DRK we have in FF is Cecil and no matter how you cut it, he is the designated tank of the party the entire game, especially as a DRK. And I do miss Delirium lowering INT and Rage of Halone lowering STR.
