It is hardly as if slicing is incredibly over-valuable now, I have spent many hours of mission time on slicing missions, forgoing another crafting skill on one of my characters, in return I have about 140k after getting to about 380 slicing -- hardly game breaking. Had they gone about fixing actually disruptive issues, like pvp health bars not working, non-functional follow and horrific (I mean horrific) UI and customization, it would sit a little better with me. However, the amount you could make from slicing was hardly worth prioritizing above any of those issues.
If you nerf the monetary rewards of slicing to nothing, I fail to see the point of the skill... Hopefully it won't be as bad as they made it sound on the patch notes.
