Don't do chaotic raid again

[Absurdity]

Your logic is sound but the bigger problem is who was this content actually designed for

When they announced “chaotic alliance raids” did literally anyone want “24 man single boss roughly 1-2 floor of savage” difficulty

Whether the devs actually said it or the community played telephone with it this content seemed to be roughly designed as the stepping stone to extreme, not the stepping stone between 1st and 2nd and 3rd and 4th floor savage

That's an entirely separate issue, the fact that the devs are apparently incapable of designing anything but "boss in circle/square arena spamming mechanics at you".
I don't think when we heard Chaotic Alliance Raid that anybody thought it would be a single boss in some arena in the void again, basically another extreme/savage fight but with 24 people.

But that's not a problem exclusive to this particular content, it permeates a vast majority of the game.
Savage? Single boss in symmetrical arena
Extreme? Single boss in symmetrical arena
Ultimate? Single boss in symmetrical arena
Dungeons? Single boss in an occasionally not symmetrical arena
Criterion? Basically another extreme level single boss in a symmetrical arena...but this time it's only 4man

I wasn’t really referring to “single boss in circular void arena” I was referring to the level of the content, I don’t like the single boss in void arena cliche but that’s not really my problem with CAR

Basically the same problem as criterion normal. Did we really need another “different” type of content that also falls into the same range of “hard extreme, first/second floor savage, criterion and now CAR”.

I'd say it falls into the same category as the singular boss in symmetrical arena, the devs being incredibly limited in their ability to design new content.
It's like they're using templates and they only include:

1. So easy that you can pretty much ignore mechanics, play on auto pilot and succeed with no effort required.
2. High amounts of coordination, only barely survivable or not at all if done incorrectly, lots of wipes to solve mechanics through trial and error.

There were literally people taking a damn BREAK from this game.

I'm sorry to say but if all you did was get 710 gear about a month into the expansion and then took a 5 month break then tough shit.
As I already said, I consider "trying your best" to also include showing up with at least current buff food and in the best gear you can reasonably acquire by playing the game at the level you are able to.
This means not showing up in the bare minimum gear just because the duty technically doesn't require more. MSQ trials technically don't require any ilvl, doesn't mean you should just show up to Everkeep normal in your level 80 tome gear.

It's not like getting 720 is some kind of unreasonable hardcore-only grind, you can get that done with nothing but some gil and roulettes in a short amount of time. But god forbid people actually have to play the most basic content for a while to progress their character enough.

People also try this out because ilvl 710 basically IMPLIES catch up.

Does it though? Savage also only requires ilvl 700-710 and for that it sure doesn't imply catch up.
None of the previews they showed implied that it's some freeby catch up gear thing, only that it's supposed to be a 24man fight somewhere between extreme trials and M3S in terms of difficulty.

And for your information just in case, I AM >720 just sadly one damn ilvl below 725 that people decide to lock this crap behind for whatever reason

Now that is probably the only valid complaint, the requirement is clearly set up to filter people out who only managed to get the so far available catch up gear.
