I will have to vote for Runecrafting. I'm not sure exactly why I enjoy the skill but I just love to create runes and then use them all

The abyss is awesome too, that was a great addition for the Runecrafting skill. RCing is also a GREAT way to make money if you are really serious about it. 40gp per ess and no telling how much profit you can make out of just one ess if you have high lvl RC :huh:
If I didn't vote for runecrafting, I would probably have to go for thieving as my second favorte. Thieving is an awesome skill too, it allows you to go many places and skip over several things in runescape. Plus, thieving is one of those relaxing skills where you stay in the same location and just hang out. Great skill to train with friends
