Makes sense. I remember Jagex saying ages ago how they want to make skills have to options, one that makes money and one that provides faster experience. Which is why they added ivy into the game for Woodcutting. I can see them doing the same for Runecrafting.
I really hope that the xp/hr isn't increased by much at all. Runecrafting is one of the only respectable capes left out there at the moment. I would be happy with an alternitive training method but I would really like to see runecrafting still be the hardest 99 in the game by far.
