Specifically from a BLM point of view: If you are doing 2nd coil and getting high allagan armor, you are NOT going to need that accuracy from the laevathin (spelling). If you are NOT getting 2nd coil gear, you will need the accuracy. However.. it should be said that the only content you really need accuracy cap 471 for is.. well.. 2nd coil.

My honest black mage opinion? Get the novus. Because spell speed and determination (or SS, DET and some PIE to get to 251 natural PIE) is WAY better than the insane ACC and moderate SS on the Laevathin.

Also... dat glow.
