This game prepares no one for raid/hard content

People get to 80 and don't even know what a stack marker is lol.

Is that so strange?
There are very few stack markers in the mandatory dungeons and trials, and you can often get through them even if you failed the mechanic.
There are a gazillion different markers occuring through the various dungeons, trials, and raids, and the game never tells you what any of them does - you have to learn through trial and error.
And even if you have seen a stack marker before, and know how to handle the mechanic, you might not know that it is called "stack marker" since that term is never used by the game.

The first time you encounter one in a required fight is during the 3.3 trial, and it's also one that reinforces the notion of staying put inside of that attack since it follows up with more attacks that have to be shared.

By the time you've reached 80, you will have encountered in numerous times, including in required MSQ fights at 70 that have the NPCs stack with you.

So yeah, not knowing how the mechanic works by the time you've made it to 80 is just a little strange.

While the game never actually calls them by any name, stack markers are all over the place from Final Steps of Faith onward, in both dungeons and trials. Susano, Lakshmi, Shinryu, Tsukuyomi, and Titania all come to mind, just from fights required by the main story.

"Very few" I could list all the ones that you absolutely must see by the end of the MSQ, and even filter out the ones that won't probably wipe you if you miss them - in fact there are even solo duties that'll kill you if you don't stack up.
There might be loads of different "markers" occuring through the dungeons, trials and raids to 80, but the most common ones are red overhead, purple overhead and yellow stack. You learn through trial and error but by 80 yes, it is very strange if one hasn't killed you, or you see someone else get killed by one. It's very strange and also extremely lucky if you make it to 80 having never had a group sit through too long on a boss due to multiple wipes from a lack of damage soaking.
"And even if you have seen a stack marker before and know how to handle the mechanic, you might not know it is called a stack marker" - I'm not sure what the point you're trying to make here is, so I'm simply going to automatically assume you misunderstood my post. If you see a flashing yellow symbol or whatever you want to call it that has arrows literally pointing to the affected player, removing all the weirder savage/extreme ones out of the occasion - yes, you should know by 80 what action you take when you see one. The same way general common sense should be used that if you have a debuff that when it expires, is going to hit everyone in the affected area vs one that is shared damage to an area, the two don't go on top of each other.

I find this defence very odd, sorry.
