If you want to get rune crafting levels up you should probably make earth runes since the earth temple is so close to Aubury's rune shop so you can get the essence anytime you want.
My combat level is 34 I think and I usually mine coal, Rune Essence, make runes, smith, and stuff like that as an occupation. Not that it matters anymore Because of my brother.
I actually haven't played it for a month or so at least and my mother might ban us (my brothers and me) just because one of them (my brother who has joined CF as "fireblaster") was hanging out with guys who intended to go into the Wildy and start killing people (possibly not including him).
But getting skill up is really tedious. Like smithing; you have to go back and forth and back and forth and back and forth Between Falador and the mines and sometimes I feel like going absolutely nuts or sleeping:sleep:.
