Why does there need to be all these third-party websites for an in-game feature that should do it just as well? Or does SE not have the "capacity" to gives players in game a way to track Hunts?

I have only ever fought hunts when stumbling on them or a shout is involved, is there nothing in the game to tell me when something is going to spawn?

e.g. having xivdb mimic lodestone is cool, but why do these hunt sites exist OUTSIDE of the game? o.0
