I rank production skills to produce things, not for stat bonuses. The ordeal is considerably more fun if the skill is difficult, too. Thus, I rather love these new additions~
I'm sort of the same way - but I'm finding engineering a bigger hurdle than I expected. The sheer numbers of items required to train the higher ranks are really taxing my patience. It pretty much just comes down to how much patience do you have when hunting for cores.
As for magic craft...I expect it'll be easier than engineering, but I'm no longer planning on getting r5 before the end of the life skill event.
