Meh, only thing (which is rather large) I don't care for about Nexus is how I'm pigeonholed into staying that job while farming lights. Atma you can farm on any job with zenith. Animus you can gather the currency for the books as any job. Novus you can gather the alexandrite as any job. Nexus... you're stuck.

I have a PLD Novus I'm gathering lights for, and frankly it sucks that I feel obliged to do everything on PLD. It feels wasteful if I'm needed to go on another job. Kinda wish that we could get a lesser amount of light on eligible encounters for all soulglazed relics in inventory as well as full/bonus light for the one equipped.
