You mean, like a book? It actually fits rather well, like a lot of things from Arcanist once did.
But to keep it on topic, I'd rather the variation that comes in the Summoner AF armor actually gets than most other jobs. It's never really my style (Can't do the horn justice if your headgear slot's always taken), but at least each set is clearly distinct so that everyone can have their favourite one. To me it's also a good way for them to refer back to each Summoner in the series without letting that bleed into gameplay.
