Pet Jobs in FFXI were totally broken and were not 'fantasically handled', they were a complete mess - BST couldn't even get parties until SE added the Jug monsters and even then it was only once they added that overpowered beetle one that players started to use BST in party situations - prior to that party leaders were usually reluctant to bother inviting a BST unless they were forced to having no other choice (namely, no one else seeking a party at the time). SMN was "just use Garuda and have her spam one or two abilities ad nausum" (and manipulate certain gear with special effects to overcome the MP-drain penalty of having a summon out in FFXI). PUP was just "BST mk II but with customizable pets".

FFXIV has shown all too well the problems with pet Jobs, and alas it's clear Yoshi has realized this, so I'm pretty confident to say we won't be seeing the likes of PUP or BST here in FFXIV (to say nothing of Yoshi's comments in the past stating how future Jobs will be "completely new and unique to FFXIV", and thus won't be a reoccuring Job from a previous game I'm afraid.).
