If you get your Range up you can be a pker not just a rusher, stay 50 attack.
Maxed 1 defence, 50 attack pures are rare and valuable. Dbow - Maul combo is a better choice then claws.
You can max out at 13 prayer and be 73 combat, you would own. I can get into more detail if you wish, why 50 attack is better.
