so why the devs never use 90% of the content for end game?

They would do well to look at how the likes of WoW, ESO and Lost Ark make use of their open worlds. Encouraging players to explore and uncover hidden secrets isn't a bad thing and helps make FFXIV's zones have more relevance beyond occasional MSQ quests and gathering nodes.

Yes, like the blue mage. With this job every player did thoroughly rediscover every little details of the overworld, going from some mobs to another, thinking with excitement "how come i did never see this place even existed ?" and "i wonder what this mob attacks are, maybe i will learn a good skill ?".

Just joking, everyone did watch at some guide to get rid of "exploration" and "hidden secrets" as fast as possible.

Like they do with raids? What's your point? Everything in this game can be boiled down to just following a guide. May as well turn it into a visual novel, in that case, and strip out all gameplay elements, because you can use a guide.
