I have Biochem on my Shadow and I've hit a bottleneck I'm having a hard time getting around. I can't seem to find nearly enough Luminescent Cell Cultures (calling it LCC) to get over the hump and into the next bracket of recipes. I will find/scan Green Goo and Dielectric Cell fiber nearly 20:1 even though the LCC is used to a higher skill level (still used in recipes long after the other two are not).
I've looked at Torhead and tried most of the places listed in the comments but the drop rates in these areas area astronomically low. I'll gladly grind this stuff out if I can find the right area...but 20:1 is really bad
