Please consider a well-stocked NPC pet shop. Every other job with expensive consumables now has a NPC that sells their tools. This helps to regulate the price from greedy crafters and also helps to make sure a player is never screwed due to low stock. Right now i spend insane amounts of gil weekly to stay stocked. And sometimes i go to restock and theres none for sale. That is terribly disruptive for me, especially if it happens on my petshell event night.
Also, on a side note, I have always thought it would be neat to have a beastmaster AF quest line which upon completion would reward a beastmaster with a choice of a personalized pet from a list of more rare types of monsters. Ex. Kraken, opo-opo, hex eye, ect.
