You are wrong on several points. First, you cannot level any crafting skill for free. Most crafting skills require a mission-based credit sink skill like diplomacy. Secondly, you assume that everyone is taking slicing. This is false. It's great that slicing is "supporting you in your 30's", but if someone decides not to take slicing, how do they compete in the economy? Myself, I rolled alts specifically to run slicing missions. This is poor game design. The primary credit faucet should come from running missions and not a money crafting skill. If people do not like crafting, they can make money doing things they like such as fighting and running missions. It is not necessary to trivialize the crafting game. This is not to mention how badly slicing will be abused by credit-selling companies. Slicing in general is poorly designed. It goes against everything we know about how to make a successful MMO economy.
