Right now Forsaken Isle is the place where end game players go, get some rare drops, then never go back. There are no incentives to go and its far from the normal circuits.
On the other side, there are certain game mechanics that desperately need higher availability due to the influx of new players, particularly mining (obsidian/linstanium in Lamavora) and Legendary fishing.
Why not combine both?
Forsaken Isle already has caves (for ores) and ponds (for fishing) , it would make it way more playable for end game players if it had ores/fish areas.
This change would also reduce the pressure on obsidian mining since a person wouldnt be able to camp in the Lamavora caves and literally hoard the obsidian supply of the whole community.
