What could DRK have learned from FFXI?

[Seku]

Since when did drk in tactics ever hurt itself to do damage? Its 2 best attacks did damage and healed hp or mp it used heavy armor. 2 games did drk ever hurt themselfs to do damage IV in the jp version only and xi with souleater thats it. You could say x-2 but again the drk had so much hp it didnt matter and you paired it with a chemist spaming hi potion.

Drk cecil only had one fight that was mildly even challenging in Milon. Just because his damage was terrable because undead and his dark element swords. And even that fight was easy with palom and porom because twin plus fire done.

1. You pair it with a Ragnarok accessory and you don't take damage from darkness in 10-2. But typical game play style requires you do take the damage.
2. For tactics you have abyssal blade and Unholy sacrifice. You also have Vehemence which increases your physical damage and lowers your defense.
