Jett's Core Aura is glitchy

When I found out that the thing will rank down on its own (when the time limit runs out, if you lock it) I decided to just not spend NX on it.

Adding on to this, the Star Dusts that drop from mobs (and cost about 200k a piece in the FM) are decent enough. I don't think it's worth the NX unless you roll something like 30 ATT/stat, and even then I'd only use the 30 day locks to hold it at that, I wouldn't cube it to get to that point.
