Im split 3ways between Rc, Slayer and mining. Reasons: RC: Impossible to gain xp quickly without using runners.... Slayer: Only way to level is doing tasks most of which give very small xp (but, gives secondary xp) Mining: Constant clicking! There is no mine X feature like cooking or fletching, and it's not continuous like fishing. So overall probably mining... "Im split 3 ways.... :? lol"
