Not like its particularly hard if you just push through the content. I've been side tracked a lot, and have done every quest and im level 44 on my 1 toon...i work etc and could prob be 50 if i was actually rushing.
I'm doing it at low levels and really its not hurting my money at all...biochem/bioanalysis/diplomacy. Bioanalysis is mostly for mobs and i get most of those mats that way so i don't need to do those missions. And the diplomacy mats are for purple/blue biochem items so i run diplomacy whenever i can and then do what crafting i can...re it and then diplomacy. But really 100-300 is cheap.
