In FFXI, beastmaster was already considered to be a solo job and YoshiP has stated before about his distaste of pet classes so I wouldn't really count on us getting a fully functional beastmaster job in this game. The pets we do have keep getting nerfed every expansion as well.

In defense of beastmaster though, we have beastmaster NPCs showing up in the Bozja storyline so there's that.

Regarding the potential of a scythe wielding job though, scythes already exist in the game as BTN equippable items so I wonder if anything would need to be renamed.
