So, what is the hold up on Beastmaster?

Beastmaster captures and use pets. This will not be possible.
I've played MMOs with this mechanic, there was always a pet superior to the other and most of the time it would break the balance.

So what? FF14 is a braindead easy game. So what if one pet does 2% more damage than another? PvE isn't competitive. And if pet balance really is a problem, just do what WoW did and allow you to stat swap pets so they all have the same level of competitiveness.

Considering how terrible pet AI (especially pathing) tends to be in MMOs, I suspect they probably scrapped the idea even if they had ever considered it seriously. They've already pretty much eliminated pet function for ACN/SMN/SCH and haven't touched Chocobo Companions since HW.

If FF14 devs can't be bothered to fix pet pathing then they could just take the lazy route like GW2 did and give the player the ability to teleport their pet right ontop of the target, bypassing pathing issues. Problem solved.

We're not talking about damage alone but mechanic as well.
What if we could capture a Morbol or Malboro and have it spew its 30 debuff on the ennemy?
Could you get the Mist dragon and freeze the ennemy?
What about the size of the ennemy? You'd have to be able to hide it or reduce its size.
What if an ennemy is able to heal, wouldn't it be broken?

You'd have to limit the possible capturable monster, then limit their utility and remove all flavor until all that remains is a cosmetic with stats.
You'll have to limit the job, for the same reason that Blue mage isn't playable in high end content.
