Since we're getting a Bloodborne themed class in Reaper, how about...

We get demon/voidsent exorcist whip wielding job class based on Castlevania's Belmonts? :3

Obviously not now, but sometime later down the line in the expansions after Endwalker. xD

Only if we get a Devil forgemaster like hector/Issac

That would make a really cool spell caster job class! Though sadly, I doubt Yoshi-P would want to make such a class because of the issues we already have with Summoner. Maybe making it like Machinist and Reaper temporarily summoning a voidsent ally to do an attack pr skill could work. Maybe more like Yuna's fighting style in Dissidia Duodsim.

Looks more like an Edda based job to me. Bloodborne did not invent scythes.
