DRK tanking. A little bit of pain.

[JackFross]

The complaint of mana cost on the single cheapest expenditure of Mana in the Dark Knight's arsenal - the skill with the highest mana per potency yield across all skills (save arguably Carve and Spit) - that's silly. Especially for groups of mobs, where your Mana is literally infinite for 15s, during which time a DA+DP (which is 250 - more than twice as much potency as Abyssal Drain (120), for the record) is essentially cost-less for one of the strongest AoE skills that any Job has access to - on a thirty second cooldown.

Please.

It's stronger than Holy and Flare and Painflare (200) and Dragonfire Dive (240) and Geirskogul (200) and Elixir Field (220) and Katon (180) and Doton (240). It loses to Assize (300), Deathflare (400), Decimate (280), Kassatsu-Katon/Doton (270/360), and Flaming Arrow (350) - and that's it!

So let's make it stronger by having it become essentially costless. 1000 health out of 25000 is literally nothing - actually negligible.
