i mentioned making guides that turn a better profit in his other thread and then he makes one that makes even less cash. There's no point in exp wasting doing this when you can just make this cash training skills...
What makes you say that? Anyone who wants to make money off Runescape in real life are going to do it regardless of whether or not they have something to spend their cash on in game. I agree with the other part of your post though.
Platelegs are 1m so I'm happy about that. They covered the cost of all my runes/ potions/mystic &farseer so the skirt and all the money I made on rune limbs/ items/bloods/d bones is pure profit and I still have like 1.5k casts left.
