I got my gatherers to 60, without doing blue scrips... Mainly just doing GC turn ins, and getting stacks of what my crafter's needed. I then had an FC friend make the white gear set for me, after I gathered the mats. Did a few simple melds (all 100%) and I've been good for everything aside from HQ folklore. When my crafter's caught up to 60, they could easily make their own white gear. So I assume if you been cross leveling ask you could make your own gathering white gear.
