Hello. I've never crafted before, but I was looking to start into it. Currently I have a Monk near cap and a Scholar/Summoner near cap. I like the monk a lot more than I like the Scholar. From what I've seen on the forums 5 materia gryphonskin armor seems to be the best.

I was wondering is it worth leveling leatherworker just for one class?
Is leveling culinarian worth it? Does food provide enough benefit or is it expensive enough where it would be worth making my own?
Is putting 5 materia in gear difficult/expensive?
How difficult is Leatherworker to level and what is a good disciple of the land for it?
How difficult is Culinarian to level?
