Actually in most FFs DRK are heavy armor dps with magic abilities. They rarely were the top heavy armor but instead armor much like scale mail in XIV. I think FFT is the only game were they wear the top heavy armor.
Sometimes they do not even have absorb skills and just have HP draining skills

I mainly remember dark night from FFIII and FFIV and i kinda used them to tank/dps but i guess the reason is because they gave the option for heavy armor, not just scale armor.
