Please don't join endgame content with a job you dont know how to play

Your analogy isn't appropriate for this situation.

If you read a book on how a Guitar is supposed to be played, then even if you've never played one in the past, you know the basics like how to hold the guitar, you know that you're supposed to use a pick, etc etc. You don't read a book on a guitar, and try to hold it like a cello, and play the strings with a violin bow. You will never become familiar with playing a guitar if you didn't read the book well enough to know how it's held, or how the strings work - to play efficiently it would be the equivalent of an AST knowing that pairing Celestial Opposition with Luminferous Aether grants you more MP. Or that Lightspeed grants you instant stoneskins. Not something you'd learn from reading the skills like you would read from a guitar guide, like hey DONT USE A BOW on a guitar like you would on a violin, or don't try to stack your shields with another SCH or another Noct Ast.

If you just got finished reading a book on playing a guitar, you don't immediately jump into playing professionally in a band. Your example seems very contrived in order to suit your agenda in the conversation, which leads me to believe that you're only arguing with me here for argument's sake.

My analogy is actually very appropriate for this situation. It is -entirely- possible to read a whole book or even a series of book on how to play a guitar and still hold it 'the wrong way'. Now, if you mean holding it upside down and backwards, yeah, but that's a whole other issue. The fact is that there is a very specific way to hold a guitar which you can certainly read about, but it's likely that you (unless you're somehow a natural at it) aren't going to get correct right away. There's a nuance in how you hold the neck, in how you play the strings, all of which you can read about but none of which you will ever fully comprehend until you actually do it. (Oh, and in reference to 'playing a guitar with a bow': Violin bow on electric guitar | Frank Steffen Mueller)

And no, if you just learned to play you don't immediately get up and play in a band, but what you should do is find someone else who does know how to do it and have them help you through. The point still comes down to the fact that you don't learn to play by reading, you learn to play by playing. I'm not sitting here saying, "Don't read your skills." By all means, you should be reading them... but you can't expect everyone to suddenly just understand the proper way to play their job through that alone. Many people need to practice those concepts, they need to work with them and see them in action in order to understand when they're effective and when they're not. By saying to a whole group of people 'Unless you can read these skills and know how to play your job, don't bother' you're only serving to perpetuate the very problem you're complaining about.

Maybe it's a difference in ideology here, maybe it's partly because of what I do for a living, but I'd much rather encourage people to try, fail and try again with some guidance and correction than simply tell people they're not good enough and should simply get out.
