Which crafts would you suggest as investment? My highest is alchemy 10 lol, so taking up any would be pretty much the same for me.
i have cooking leveled, and i almost never use it because even if i hold ingredients on a mule, it's hard to get inventory to craft if you normally go around with 80 80 72 or something. in addition, there's not much to make with synergy that involves cooking.
personally, i would rather have cooking on a mule because there are so many recipes that take 7-8 different ingredients and/or subsynths.
