So, what is the hold up on Beastmaster?

[CKNovel]

Multiple problems:
Pets are so much a problem SMN received a whole rework for it.
We basically have 3 types of pets in the game:
-The Glorified Dot, Automaton Queen and Living Shadow. Terrible AI, works badly against multiple targets and they're so forgettable you mistake them for players.
-The Good Bahamut&Phoenix, stands like a turret and execute Akh Morn on command. The best pet at the moment.
-The fairies, you put them in the middle and they execute order.

The thematic of 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.

BLU reception is mixed
Many players are complaning that BLU wasn't a full job and were disappointed about its limited status.
You can't enter content where it would shine such as Eureka, Bozja or Deep Dungeon, you can't queue as a Blue Mage, you can barely do anything as a blue mage.
What should've been a fun job with barely any limits is now an infuriated mess that can't access most of the content.

In conclusion
If Beast Master is released, it will be a generic job with a fixed pet probably close to the Glorified dots or Bahamut&Phoenix, maybe a completely new type of pet if they surprise us.
The best beast master we could have would be a generic job with a pokemon mini game as a side content.
