I posted this in another thread originally to... not much fanfare, but I think the idea has potential! More specifically, what I'm suggesting is a job based around Cloud's weapon(s) and fighting style in Final Fantasy VII: Advent Children!
For those unfamiliar, AC Cloud fights with 6 swords of various shapes and sizes that can be combined into the aptly named Fusion Sword, in that form not too dissimilar to the Buster Sword. If I remember correctly (it's been a while), the fully assembled Fusion Sword only really makes an appearance towards the end of the film, which was a neat detail, and similarly I'm thinking assembling your weapon is something you would work towards as you went through your rotation?
I debated back and forth whether this idea would work best as a Tank or DPS but ultimately decidedTanks have enough of a monopoly on cool weapons already, damnit!it feels less defensive and more of an offensive sort of job? I don't really have the know-how to come up with full skilltrees or etc. but mostly I was thinking maybe you had different paths (combos) you went through to slap more components on, with the intermediary stages having different benefits. One example I used originally was if, at one such stage your weapon had a serrated edge, it could apply DOT (Bleed)? This... sounds a lot like a reskin of Samurai, doesn't it? W-well, I'm sure the devs could come up with a way to make it distinct (besides aesthetically)!
I don't really have a name for it, I briefly considered calling it "Sword Saint", a recurring job in (mostly spin-offs of) the series, and I think it could work as kind of a unorthodox take on the idea since... can't get more skilled than simultaneously fighting with 6 swords (or weapons in general, in which case you could toss some Dissidia Firion into the mix, too!), right? but ultimately I'm not too hung up about it...
Could this work as another much-needed Scouting Job? A third Striking? What do you all think? Reckon it's novel enough that it wouldn't step on too many toes?
