I think one thing that should be fixed or added in the next patch, or whatever you want to call it is the Abyss for Runecrafting. It would make a lot of that Runecraft lives a heck of a lot similar if it was there in working for making nature runes, cosmic runes, law runes, etc.... It would make the cost of each rune more stable because they higher level runes are more accessible. Its something that will make the world of Runescape go around more easy.
