I have almost every skill at 400. I think they over balanced the nerf on Slicing. It used to be one of the easiest to see your return on, so a lot of people used it. But now it's harder to get a return, and it isn't comparable to other money makers. Maybe as people give up on it, the rising cost of missions will balance out. So far there hasn't been a noticeable bump in mission prices on Darth Bandon. We'll see.
