But Woodcutting and Fishing, whilst enjoyable. A lot of people find boring, doign the same action again and again. There are 3 types of skill, resource gatherers, resource users and Slayer (Couldn't think of another off the top of my head). Slayer was successful because you could train loads of skills whilst being introduced to new monsters, new drops and advancing a cool new skill. A Slayer-esque skill would be good, but maybe skilling related.
