Anyhow, the only other craft with this nature is ALC, which means that you can make money selling pots + tinker's calm.

But yeah, as has been mentioned by other people, you will need all of your DoH to level 50 to make serious money anyways. But don't be fooled into thinking that you cannot already make money even before you are level 50.

Things to pay special attention to are items that people use for leves for leveling and things which are rather tedious to craft (hint: CUL & possibly WVR things). My advice for you is to make your own spreadsheets of profitabilities and pay special attention to the history of purchases and use the MB tools to find 'holes' in supply and stock up based on all these info.
