I don't know about these three locations, but I think that dark crabs should be removed from the shop and made to be optainable from the resource arena in the wilderness. This way fishing there would be rewarding and would active deep wilderness a bit more.
Wilderness agility course is already good xp, so I think small reward of blood money would be reasonable. Like 10 as example?
Also:
-Add multiplier to the blood money for pking in +30 wilderness. There's always risk on pking in deep as it's obviously harder to escape and you always lose your untradeables on death.
-Remove the teleports to the deserted keep and mage bank. It's not realistic that you can teleport straight to the safe part of mage bank without going through edge/ardy lever. This would make some traffic out there.
-Add delay on opening/closing the gate in front of the KBD lair. Currently it's impossible to go through the gate if there's someone closing the gate while you try to open it and run through. Not sure what is done differently in osrs, but I have escaped many clans on there. On Battlescape it is impossible if there's one guy spamming the gate.
