Though the delay is high (which on the bright side opens up x-hit builds a little more), the stats on this make it a very viable target. Especially for those that don't have the means to finish the moogle trials.
That said, you trade nice looking stats for the potential of Fudo's dominance.
if you cannot for whatever reason obtain 30 decay, or do something even easier by killing carabosse a few million times and the easiest T2 Nm in the game from visions zone, then I suppose this would be a viable option only if you really really hate doing TotM and cannot bring yourself to obtain something better... I guess.. :/
