Please implement something to teach players how to play

[Absurdity]

WoW does ironically enough, and say what you want, but As a long time WoW player it was something consistently asked for, for a while. It works, people understand the basics more, and its easier for me to help them understand content more. This is my experience within that game at least and still is now as I lvl alts from scratch and new players seem to have a grasp on the dungeons we run. Note WoWs dungrons require a bit more over all from their players in terms of dungeons. Not a jab at 14, but a fact.

Edit: The system also existed for players who boosted character for the longest time. You had to do a mandatory tutorial so you can understand what a class did, why it did what it did, and how it applied to the content you did it in before you even got released into the world. It did this for each of WoWs specialzations, which currently functions as sperate classes unto themselves. FF can definiately do it in my opinion.

I completely forgot about this, there we have an example. Granted WoW's classes are a lot easier to explain imo. Since they are mostly proc based pressing random buttons in WoW already does a decent amount of damage compared to XIV where just pressing random buttons is a terrible idea on most jobs.
Is it impossible to do that with a tutorial? Absolutely not, it just requires a slightly longer explanation.
