Personally, I'd like to keep this short and sweet to avoid any unnecessary hostility and "notorious" puppetmaster rage debates over what's best for the job because there's no answer; it's completely something that's influenced by personal opinion.
I would like to know if there're any new pets in mind for Puppetmaster, this being more of a thread for the Dev team to answer rather than the puppetmaster community, but I feel that a new pet is well deserved for the weary eyed players which spend so much time asking for a bone from square enix... What I feel we really need is a fresh start, and this is feasible through a new pet. Of course, this comes with more problems in which square enix needs to fix, but I'm noticing the longer Puppetmasters are subdued to the same repeticious style, that being our current pets, the more time we spend fixing the old things including AI workability and flexibility during a fight let it be with a NM or a normal mob. Now let me say this... I understand that many puppetmasters are more than likely tied over with the current pets they have, but I doubt you or any other would complain to any faction of advancement or improvement to the puppetmaster versitality in which makes us so unique so I hope that all of you can remain at least optimistic to the ideas I put out for pets.
A Monk type pet or another Pet "Head" piece in which prioritizes enhancing magic are two pets I would look foward to because a Monk pet would hopefully introduce the concept of using two hands to fight instead of one like all of our other pets and be able to hopefully hold his own like Valor Edge but still be able to dish out damage like Sharp Shot allowing for the master to worry less about his pet. As for the Pet "Head" piece, I would hope it would have high elemental capacity where you could possibly switch intoit quickly no matter what attachments are currently on the soul souther frame or red mage frame set up and quickly cast enhancing magic then switch out once you have what you need like protect, shell, and haste (This would also call for Square Enix to allow our pets to cast enhancing magic outside of battle like NPCs.) Possibly even be able to switch into it during battle...
Feel free to add pet ideas and hopefully a Dev will comment telling us whether or not a new pet will be coming out soon. They have been being seemingly benevolent lately answering our many questions about Puppetmaster fixes and patches so hopefully they'll comment here too.
