I find it hilarious that SE are working on changing pet rolls, when the issue really is that they only effect pets. All rolls need to hit all party members and pets. And when that is fixed, you need to change BST, PUP and DRG roll into something new. Right now you are sitting there and making meaningless changes to the pet rolls instead of correcting the flaws of the system.
It is also good to see that we have fixed attack BST roll, so that pet jobs will fall behind melee jobs from level 50 and forward. A handy proof when you want to talk about how SE tries their best to remove pet jobs from the game. And they got what they wanted in FFXIV.
It is kind of funny to read about the Gallant's roll defense choice though. I thought you hated Summoner when you gave Titan defense bonus aura, but apparently it was just your delusions that defense aura was the best defensive aura we could ever have.
PS. I've never had anyone ever request defense aura. Do you honestly believe someone would request a defense roll? No they wouldn't. Go change Gallant's roll to something useful, and FIX THE AURA ON TITAN while you are at it.
