DRK had abilities similar to Warrior that raised attack and lowered defense, with its class identifier skill Souleater coming in at level 30 granting +25acc and taking 10% of your total HP and converting it directly to damage dealt on both auto attacks and physical weapon skills. It basically had Blood Weapon to offset that.
Within the confines of its black magic capabilities, it excelled in Dark Magic skill, with minors in Elemental and Enfeebling skill. Dark Magic skill affected the Drain and Aspir series of spells, spells that drain HP or MP. It got earliest access to Aspir II and as far as I remember, exclusive access to Drain II and Drain III. Drain II/III allowed it to drain and add the absorbed amount to total HP, granting it temporary hit points. This looped back into making Souleater more effective.
It also had Dread Spikes, which are spikes that deal counter damage that have endrain on them, granting the DRK HP back for being attacked. Incredibly effective, but had a drained HP total effect that would cancel the buff rather shortly against anything dangerous. Damage resolution also happens first, so if the DRK takes lethal damage they don't drain it back after they are already dead, receiving the KO status.
This variation of DRK has been in FFXI online since 2002, so it's got a 19 year history, to be fair. There's people that've been playing this type of DRK for almost two decades, and for the die hards, FFXIV's is a pale imitation at best (though certainly relatively more sturdy).
But yeah, I agree, DRK overall is about lifesteal for big damage. That's why people frowned when it was introduced as a tank. The Drains and things from FFXI version were all there to augment its life steals.
Big Sadge there too, cause none of its lifesteals worked on undead monsters, and a lot of times were subject to Souleater resistance to prevent DRK based zergs cause it used to bypass all defenses.
