JaGeX just game some teaser images and devblog about Runespan: http://www.youtube.com/watch?v=S9kiR1TZ6J4&feature=channel&list=UL By reading the devblog, I think it will be like the lash power factory mini-game... Like changing the place you should go all the time, etc. I wonder how much this will affect 200m all... Also the best skill to effigy from now on will be Agility instead of Runecrafting, I guess. Also, I wonder how many people will decide to get 200m Runecrafting if this update is good.
