I hope they don't change it, as it's a great way to train and I find it fun (I often compete with friends to see who can make the most damage). It's been a while since they first released it and technically they shouldn't change it, but as posted before, they often nerf things that a) don't need changing, or B) things that are overpowered, like the rewards XP. And to those who kept talking about the "Mod Paul" thing, Jagex currently have four employees called "Paul", one being Mr. Gower, one on the Graphics Team and two on the Customer Support team. Click me! for proof.
