Yes but isn't he trying to get crafting experience? the point is that you're still losing gp, as long as the cost of mats are more than the high alch value. the only good point is that the gp lost is spilt over 2 skills, crafting and magic. But he is not losing gp, 3k hides 4.5M tanning 60k 1k rune essence 85k = 4,645,000 Okay after he makes the natures and alchs he gets 4680000 gp how is that a loss if what his main goal is to get crafting experience not bother about some kind of potential profit, last I checked his goal was to get crafting experience; not money. to me, crafting nats is for the profits.. of turning a p ess (80gp) to a nat (300gp). if thats not your goal in runecrafting, then using this method will earn you a small profit. however if you see runecrafting as a money-making, then you'll be losing money as you wont be able to sell your crafted nats.
