Believe it or not, slicers were supporting the economy more then hurting it. I guarantee if you were to pull a number on GTC transactions before and after the nerf you will see a HUGE decline as people will now be completely hoarding all of their credits.
Slicers were supporting the other crafts by actually spending money on crafter wears as upgrades to their gear, now since slicers wont be bothering anymore u will find the economy in even worse shape as noone will be buying anything that cant be easily replaced through other means... questing, pvp, FP's, op's
