Summoner doesn't feel like it Summons.

Yuna also had permanent summons, and FFXII and XIII featured summons as temporary allies.
Let's not act as if permanent summons would be breaking any rules, the Franchise has been moving towards more permanent and interactive concepts of summoning for 20 years now; it's not as cut and dry as you make it out to be.

And then 15 was summon shows up and does massive damage and leaved. They largely choose what will fit the system/story they are going for.

It took me a moment to realize carbuncle is the catalyst for summons. At first I was confused but after I rearranged my toolbar Bahamas's attacks next to each other, followed by summons, it litterly becomes boom boom with all the instant casts minus ifrits gem.

The current system seems like a good compromise between the new and classic systems. Bahamut and Phoenix act more like the current standard where you summon the creature and it sticks around to do a few attacks. The other three act like summons worked in Final Fantasy 3, 4, 5, 6, 7, 8, and 9 where the creature is just a spell where you summon it to do one big attack, then it goes away.

If you don't count Egis as summons, then a job that only lives up to its name at one (1) level out of 89, has a massive design problem. The biggest this game has ever seen.

Yes. We have been dealing with this for the last 8 years. 8 years of trying to get Egis to work, 8 years of them not working. SE has finally stopped trying to get them to work. The engine, code, and networking all fight them combined.
Everyone will cherry pick their favorite version of summoner to be the default mode, some people even looked at the previous 8 years of "summoner" as the idea mode. Given the restrictions on classes only one group will ever get their ideal summoner at any one time.
We get it. Your ideal summoner is to micromanage a pet that does chip damage and has your spells originate from it. we've tried that and it doesn't work. Maybe they'll make a FFXIV-2 that can accommodate every style, but right now what we have is what currently upsets the least amount of people while working between their spegetti systems.

In XV Summons were also entirely out if the players control, and thus aren't much of an actual gameplay concept.
But yes, you're correct in that they choose whatever concept fits the game they appear in. I mainly take issue with the constant narrative of "Summoner must be X way cause Y game did them like this" when Summoner existed in quite a few different ways throughout history. Its reductive, so I chose to speak my mind on it.

Point being, the old version - wether people liked it or not -was just as much Summoner as the current version is, and OP isn't wrong in feeling how they feel. It's preference, and people should start treating it as such instead of constantly arguing their opinion is superior.
Just my humble opinion on it.

Even that isn't much of an issue since you hardcast the first and then swiftcast the other one. Comes out real smooth. Just like Ruin/Tridisaster > Titan Spell > Mountain Buster are also butter smooth.

Garuda you can do whatever you want. Not sure if it's beneficial to do Ruin/AoE every 2 casts of a Garuda spell.

I have levelled Summoner to 90.

The new rotation is fine. I can fit all of my abilities on my controller hotbar. It's not convoluted. No more dotting or 3 minute long rotations. It's pretty straightforward. Actually it feels pretty easy, probably almost as easy as Red Mage. You're also not punished for missing a few GCDs running out of AoEs, so this could be a good job to learn new boss fights on.

My biggest complaint is that it still doesn't really deliver on the class fantasy. You press a button, Ifrit/Titan/Garuda drops down, they do an attack that deals a measly 1.4x damage of your basic ruin spell, and then leave. They're only onscreen for like 2 or 3 seconds. Furthermore, the Carbuncle at your side is now useless. It just stands there and does nothing, not even autoattacking. It feels like your a generic mage throwing out fire/wind and yellow spells (the earth spells aren't very readable as earthy and just look like yellow magic), and oh yeah there are pets appearing every now and then on the side, but they don't really feel like they do anything.

I would be fine if Summoner was defined by doing overall low DPS dealing 7,000 damage with their basic attacks, but then had ultra high damage burst phases where a summon drops from the sky and spends 5-10 seconds casting this super awesome attack that deals tens of thousands of damage and takes a huge chunk out of the boss' HP bar. Samurai is already sorta like this with their Midare and Shoha abilities, and especially their brand new amazing Namikiri attack which two shots almost all level 90 enemies in the game and takes a noticeable chunk out of a boss' HP bar.

It would be really cool if we could also get other summons, or maybe glamour our current summons. What about replacing Ifrit and his fire attacks with Susano, and sword and storm themed attacks? The 2 casted Ifrit abilities could be Susano raising his sword and then bringing it down on his enemies.

Honestly, the original FF summoner feels like a black mage reskin. You cast spell, spell does damage. The only thing setting summoner apart was the visual fx for it.

The more modern summoner where you can actually fight alongside with them and interact - where they're more than a reskinned black mage nuke - IMO is the way to go.

FFTA disagrees with this sentiment.

BLM spells were powerful in a small area, Summons smashed the entire field and IIRC were the only things that actually could just push a button and affect the entire field.

If you want to boil away all the flavor of Summoner to "hurdur particle effect go smash", then literally every job is a Black Mage resin, now and in previous iterations.

The visual flair of a job is just as important as the mechanical aspects that define the kit.

At the end of day, A Black Mage is hurling giant fireballs and snowballs around while a Summoner is calling down Primals to blast their targets and draw on their elements to empower other spells.

I still find it strange that Carbuncle is just... there... doing nothing... just appearing between other summons
