Unless the stuff you want to craft requires monster plates or gems...then it can be a pain.
Overall, though, I don't feel like I've had to grind a tremendous amount to get what I needed.
I never had too much of a problem with those items, but maybe I was lucky. At least you can buy those with the weekly certificate things, so it's not like you'd have to grind a monster for a million years and never get a gem lol.
