I would like SMN to be freed from its 4-minute rotation, but SMN in Final Fantasy historically is not a pet job. Sure, you can argue out of all the jobs we do have in XIV that SMN, or SCH, are the best jobs for a pet job, but SMN's in the series didn't really call them in as pets nor did they hang around with the rest of the party to fight.

FFX you take "full-control" of whoever Yuna summons, she fits the WHM archetype with the magic she uses, and tell them whatever command you want them to take, but the rest of the party leaves. It would be cool if I could take control and play as Bahamut and the rest of the alliance leaves in FFXIV. Not really, but that would be funny. FFXII and FFXIII work similar to this as well but whoever summons the eikon/primal stays in battle to command them. Anyone can summon in XII and XIII.

FFIV Rydia, who fits the archetype of a BLM, calls them in and they do one big attack and then they go bye-bye.

FFXVI Clive "absorbs" the summons essence (eikons) and take control of their powers but some people literally transform into the Summons (Jinchuriki style).

Our current SMN is a combination of FFIV and FFXVI's style especially; the summons do a big attack and leave while we are left with their powers.

It's honestly nail on the head perfect how it works right now in accordance with the job fantasy. It literally just needs astral flow abilities at a reduced use in STB content (lvl 66) and it's perfect in my eyes. E.g Use 2 quartz topaz to get 1 Titan's favor, slipstream deals damage up front but doesn't leave a dot and Ifrit is just the gap closer without the combo-follow-up and then they upgrade to how they work at lvl 86.

Playing SMN in OC, Forked Tower and current extremes and sometimes it's "impossible" to do your rotation/get through all summons if you're not psychic. I'm not saying that to complain or to say "too hard" but more to say that it really shines in faster paced content. Say you use Ifrit right as Memento Mori hits in Necron EX, shucks, you have to move, be at the back and you can't use your gap closer without PvP mode activating. BLM can literally be like "Trip cast" and do anything it needs at this point. OC is a perfect example of "reactionary" mechanics and sometimes being unable to use slipstream or sometimes any of your Ifrit phase if that's how the timing worked out.

tldr; Current SMN matches FF lore perfectly. I just want the astral flow changes I mentioned 2 paragraphs above this and Shiva, Ramuh and Leviathan. Oh, and the option to summon either Bahamut or Phoenix after Solar Bahamut, our choice, then it's back to a 2-minute rotation.
