Linkshells already track hunts and many use hunt tracking websites to know when and where they are available. It's not really hunting IMO. That aspect has been butchered.

I'd say just make a beam of light when the hunt monster has been pulled so everyone in the area knows it's general direction. And doesn't need to waste time asking for it's coordinates.

Could even just make text appear on screen in lieu of Diadem and just say "you sense a dreadful presence in the area" if a A or S rank monster is alive.
