By taking slicing people lost a gathering skill that they could use to level their crafting skill, this is why these skills were designed, to help with crafting so they could sell the things they made. Sure people that made tons of cash bought items from crafters, but most people don't buy crafted items before level 50 just because an upgrade will always come. So while slicing makes people leveling up tons of cash, only maxed out crafters make money off crafting, when most people need the money before level 50 to pay for the overpriced skills and speeder training. I knew having an inquisitor the best crafting skill for me was synthweaving, and with that being true I knew the skills to help those were UT and Arch, which have a profit loss every time. So why should one gathering skill make tons of cash when the others aren't viable till max level?
