Just a minor note; even though the profession guides are useful on major parts, it's far better to use any available ingredients you have first. Might end up getting more skill ups and then skipping some parts of the guide itself. I've also found some alternatives to be better for skill ups than what the guide suggests.
It's a shame there's no farming guides for herbs. At least I've found the one for ores to be absolutely perfect! At least when it comes to obsidium... 'nuff said.
