What exploit?
You simply need to learn to save on skill and stop spending on skill you won't use at the end.
Get gears from Commendation, pick up any trash items and sell to vendor.
I have Slicing. I pick up every lockbox I see and rack up about 100k per planet during leveling. + 200k quests.
I'm not lazy and I do work full-time.
How hard it is?
Right now I ahve 800-900k left, after all the Speeder level 3 spending and speeder.
Today I just rack up another 200k from PVP and Questing some places and spent a bit on materials to get some epic crafting.
