I don't think whip is unlikely for any ethical reason, but I do think it's unlikely because FF14 already somewhat established Beastmaster as archetype within itself as "one-handed axe + shield" thing, with like half a dozen different named Beastmasters from Bozja. Of course, there's possibility of them saying that its just regional take on the job or something, but I imagine theyll lean harder into that, maybe making shield into some sort of tamer's glove, and turning the weapon combo into single weapon.
