Old School Runescape

Looking on the wiki, it feels like some skilling guides don't take into account the opportunity cost of grinding other skills or grinding for gp. Sure, I can buy logs for fletching and get 100k xp/hr, but that doesn't take into account the 100k gp/hr required to do that. It's not really 100k xp/hr anymore. There's also fletching broad arrows, which the wiki says "are not very useful for anything" and are also expensive. It feels silly to make a ton of resources that are just going to be thrown away, when instead arrows can be made to level ranged.

The most efficient skilling methods also seem circular. If I want to grind x I should level y, but I need z to be efficient. And to get z I need to grind x. There's also what feels like a lack of skilling options listed. Sometimes I want to do "dead content" for the fun of it.

I'm definitely just a noob, but discovering new stuff to do is hard sometimes. I also am aware that I'm contradicting myself a bit by wanting a more efficient guide but also wanting dead content lol. But anyway, are there any resources available that might help me out?
