My buying them with CC does not affect crafting at all as they are already on the GTN and going for 300k and up.
Absolutely untrue. The mats alone to make a single ship part cost nearly $1 million credits.
None of the parts on the Jedi Covenant Server are crafted; they are all put there from straw purchases off the Cartel Market. How could I tell? No crafter name tag on a single one of them. Why would a crafter even bother when they are undercut by 70% of breaking even?
