How do mining skills/professions factor into things? I have been concentrating on hinting but would like to do a bit more mining but I'm really tired of getting useless materials. What would be the drawback of using a better Mineral Finder with low (as in 0) profession levels? Does it work like weapons in that the efficiency will suck until I reach level 4 or so? With a level of 0, would it be good to use a F-101?
