I created an infographic with nice pictures to explain what my idea is exactly, you cand find it here on Reddit: https://www.reddit.com/r/2007scape/comments/1j0napt/repurposing_the_area_west_of_falador/
The idea boils down to repurpose the area that contains the west Falador mine and the dark wizard's tower.
Currently this member-only area is honestly dead content, people go there for the Fairy Tale quest and run through it to get to Taverly or Taverly dungeon. (not certain if there are any clue steps here)
The mine consists of tin, copper, iron and coal... All of which can be mined at better locations in the member world.
The dark wizard's tower houses some NPCs with drops that are not even that desirable in f2p.
This is why I would like to propose making this area f2p and adding the following.
