Is it worth using aoe skills during LL in TEA? (DRK)

[VenKitsune]

Or other parts of the fight that feature two targets, for that matter?

I know for some of the tanks it is - PLD, WAR (Not Decimate or CC) and GNB i imagine do, just from some top of my head maths, incase anyone clicking on this was wondering, but feel free to prove me wrong....

But what about DRK? Obviously its a gain to use Flood (300 pot per target, as opposed to 500 on one), and a loss to use quietus (210 per target...vs bs being 600 on one, no contest)...But what about Unleash and stalwart soul? Its the same blood gauge increase as souleater, the same MP gain as SS, all rolled in to two GCDs...Buuuut those two skills are spells, they scale with spell speed and not skill speed and so i dont imagine you'd want to do it during BW windows, as you'd only get 4 instead of 5 attacks in...And it sounds like it'd really screw with some timings.

On paper it seems to be worth it but...Well, i suppose i just needed a second opinion, perhaps from those who are doing or have done the ultimate, and while you're at it, any general advice for post LL as DRK would be useful too!
