Get one more RC level and use the World 16 Air Company. What you do is you get a load (i mean a mother load, like 20k or something) of Noted Rune Essence along with Load of Cash, wear black robes, and runner will come looking for you to trade. You trade them 25 noted ess and 2k cash for their 25 unnoted ess. click on altar, move on to the next person. lather rinse repeat. You pay 1 ess and 80 gp per ess given, so about 100gp ea. Selling 6 airs at 15 ea yields 10 gp loss per 5 xp of rc, thats 2 gp per rc. This gets flipped when you get 66 rc, when you craft 7 airs per ess. you GAIN 5 gp per 5xp of RC xp. Does it look slower than Laws, on the outlook, it does seem that way, but the MOST crucial thing is that Law Crafters need to run a fair distance, as well as waiting for loading time, and in that time, you could have easily gotten 2 trades on world 16 and crafted them, thus completely balancing the total xp gain per hour. I would recommend that.
