I felt my previous responses had explained the situation adequately, but apparently not, so allow me to try again.
First, let's rule out individuals with diagnosable physical and neurological conditions that prevent them from playing combat well. Keep this simple.
Your assertion is that everyone playing FF14, when given the required information, can clear Savage. I think to be fair we must also stipulate that this "clear" involves them not being carried. Okay so far?
For this to be true, Savage content must require an intrinsic level of skill that is below the minimum achievable skill level of all players in 14.
Skill is not some binary, in which absent of disabilities you can do all content in FF14. It's a spectrum. No matter how much information you give people, and how much they practice, each individual will eventually reach a skill cap. Even you Volgia!
Let me try this from the opposite direction. Think of a mechanic you find difficult to handle. Now imagine that the cast time is shorter, or the speed of the attack is faster, or the number of pixels you can safely stand on is reduced. Can you now resolve this mechanic? Can you resolve it if these parameters are made increasingly more difficult?
It seems that because all it takes for you to resolve savage mechanics is information (which in your case I assume is obtained through progging), that you have concluded everyone else can do it too, if only they would try.
This is completely false. You're really good at this. Possibly abnormally so. Most people are not at your level, nor can they achieve it. This is no more controversial than noting that different individuals will have an intrinsic limit on how rapidly they can unscramble a Rubik's cube.
Now I would accept that some people who currently do not attempt Savage could do so successfully if they put in the effort, but this idea that the bulk of the playerbase is not attempting Savage because they are lazy is frankly offensive. Not only is it beyond their current ability, it is beyond their achievable ability.
