Not strictly related to LNC, but I'm not comfortable on melee classes unless I have at least 400-420 acc. Somebody parsed me on Ifrit with about 420 acc and my hit rate was around 99% if I remember correctly, so you can still miss with that. Anything below 380 is just way too little unless you have a BRD acc buffing you. Getting high accuracy should be the main concern before trying to reach cap stats, in my opinion. Of course DRG has the back-up combo for missing but I still wouldn't go for low acc just to use it.
