I think the developers need to look more closely how pet jobs have been abandoned by the traditional role playerbase. BST and SMN in particular have been forced to go do their own thing, and we do it very well. PUP seems to have disappeared from Abyssea entirely.
The problem is, that pet owners get EVERY buff available except COR pet buffs, and pets only get Atma and COR buffs. Pets do not benefit from the same gear that buffs the owner. Pets alone are not as powerful as a single WAR/MNK/NIN/etc. Pet owners alone are not as powerful. When you buff either the pet or the master but never both, these jobs fall WAY behind a job that gets the full benefit.
The effect is that the pet owner could be the more powerful than the pet. For DRG, this is intended. For BST, it's always been close. For SMN, it's just crazy that the player can pull hate off the avatar.
I think a few key adjustments would make the whole experience much more enjoyable for pet jobs:
1) Allow /BST subbed Snarl to work for Avatars, Wyvern and Automatons. I really don't think DRG would use it, but why not show them the love too?
2) Allow all avatar buffs/heals to at least hit other avatars, but I vote for all pets. 2 Garudas should be able to heal each other.
3) Put back in the code that allowed pets to benefit from DNC Sambas. We loved this "error."
4) Enhance COR pet rolls to account for the fact that no player will benefit from any rolls.
5) Introduce AOE pet food that works on all pets in the pt.
6) Please please please introduce armor for SMN, BST, DRG, and PUP that equally buffs both the player and the pet.
Specifically planning to buff an Avatar for Haste, I can reach 30% pet haste with Hastega, Augmented hat, and Atma of the Omniscient. This comes at the expense of both the pet and the master. This expense does not exist for jobs that can easily reach the 80% delay reduction cap.
Pet jobs are not weak, compared one by one to other jobs, but they have been left out of nearly every benefit received through teamwork.
