I suggest ochain. I have ochain and i gotta say it really turns the job around. It becomes a hell of a tank for VW maintaining 90%+ shield block rate even without shield skill gear on. And those NM usually hit fairly hard, so you're mitigating 200-300 damage per swing, this allows you to keep your hate capped a lot easier as well as reducing your healers' hate.
I started this shield casually, collecting plates during ls runs or shout groups whenever i saw one. This step can be knocked out in 1-2 nights with a group of 4+. Souls stage is pretty annoying, if you havea group with you, get away from altepa and your competition will drop drastically. For a group of 3-4, estimate 1 hour per T3 NM (this is factoring in convertion rates and comp and the souls drop double about 70% of the time) Azdaja horns, easy with brews. Farm KI by killing deelgeed and aoe farming gold boxes, super quick. Then multi-brew him with non-darkness based WS (he resists dark like crazy).
Aegis is of course also a solid shield. You'll never get one shot from a quick casting spell or JA. However from parses i've seen, aegis' block rate falls off to 55-65% during VW.
Aegis would take a group of 3-4 about 1 to 1.5 months to farm currency for. Less if you have gil/can make gil to buy currency as well.
@Fynlar: i often soloed koios on my dnc/nin solo, and you must have some terribad dncs there because i took him out in less than 4 minutes when he didn't use stoneskin, lol. Dnc's DoT is sorely underrated in abyssea due to bad dncs fulltiming fan dance and using WAY too much evasion.
