O.o
Are you suggesting that the crew skill vendors would sell you Grade 27 schematics for instant crafting of top-tier items?
What's the problem with this? All of the crew skills had rakata grade patterns available to them at the launch of the game from their crew skill vendor....when rakata was the top tier gear. The only caveat was, whatever you crafted was BOP.
Why would it be bad to do the same at the onset of the new xpac? Oh wait....you haven't QUITE enough time to make millions crafting your 27s?
