I'm using the Excel sheet I found floating around somewhere, not the Google Docs one. Even that needed some cleanup, though.
I use one of my mains as a crafter, both BS and Crafting. I've put 2 points each into BS and Crafting I rolled them with Scientist, not realizing Jahan also has that. I found that only a single point into both allowed me to do well enough for quite some time, mostly repairing and making potions or quills to increase income. I begrudged the skill points a bit, but found them necessary. That's a Rogue, so it was easier than on Jahan, I suppose.
