You did a really good job being concise and to the point of the concept. I've been a fan of whip-type weapons since FFVIII's Quistus, and Type-0's Seven.

I think it fits into the Scouting role nicely. I like your break system, which was my favorite thing about XIII's combat system along with paradigm shifts.

Despite it not really resembling a Beastmaster like in Tactics Advance, just like SGE, it doesn't have to be the exact replica and I think that this type of job would fit into the world of XIV.

That being said, I don't think the devs will do it though. People would be expecting a full on pet job and they've made it clear that pet jobs do not work in their engine. It's either too slow and unrespni or outright broken.

I guess for the devs with pets is that it's like they have to balance both pet and job and I suppose that's too difficult for the team (which begs the question of hiring new blood for the job design team).
