The Crafting System is horribly flawed as is. You need for every item that you want to make 30 of the lowest grace material tier (L) and only few random of the specific level of the item. Problem ist you get tons of materials for your lvl every time, that you cannot use and end up as junk in your inventory. And the ones you really need drop only from lvl 1 to about 30 therefore you have way too few of them.
And most of the mines, herb fields are useless, because they produce as well for their lvl. So the only ones that are useful are the 2 in the beginner area. And even those give randomly higher tier materials, which again are useless and slow your process.
I know back in Karma there was once a different more thought through system, which was changed to the current one. It's too long ago I don't remember the specifics, but my suggestion would be to address the unbalance of the materials needed. This could be done by using same lvl tier materials more than the L-Grade. Alternatively change gathering and make the results less random: VV Herb Field give only L. OC Herb Field give only M. Etc. Best would be to combine both ideas.
Or even revert it back to the old system.. . Even though I don't fully remember it, as far as i remember it was way better.
