For a NIN this would only be helpful in lowering damage taken after all your shadows drop, because shadows sit on top of phalanx. It certainly wouldn't help you keep shadows up, although Blink might.
Well, to begin with it looks like NIN can't equip this anyway. But even if they could, I doubt they'd use it, as the poster said casting time was around 20-30 seconds, which is nightmarishly long for a NIN tank. Not exactly something you throw up real quick between Utsusemi's being down.
It would seem the biggest benefit would likely be to use this the way a NIN tank uses Utsusemi: Ni, which is to cast it before the pull comes in and have it up at the start of the fight. With the recast timer being rather long, you couldn't have it up every fight, but perhaps at the beginning of a new chain.
Though PLD's want to lose some HP so that they can cure themselves to hold hate, so it seems kind of a mixed bag. I would think this would be something that's situational. Perhaps if you're fighting mobs which tend to hit particularly hard and you want to lessen the HP lost. Then again, I'm still working on PLD; it's only 25, so I'm hardly an expert on what's best.
