I figured flint is quite slow to make on igneous. It is obviously a non issue to have 1 igneous or 2 producing flint for whatever purpose you need flint for. I personally always have atleast 1 igneous utilizing for flint and steel specifically.
But when you need like a quarter stack of igneous of flint to make you flint it becomes absolutely tedious and not quite worth it. 4 second for 1 flint with 70J/s equals to about 280J for 1 flint and about 1 hour and 48 minutes to have an igneous filled with flint.
You might ask why I am grinding flint specifically but I'll write a different suggestion related to flint after, but I can reassure you it is not related to money / anything gamebreaking, just a certain block for builds.
Now, ideally, flint is made akin to sand, produced every 2 seconds and possibly for even less J / s, maybe around 35J/s. This would make 1 flint cost 70J and halve the time of waiting an igneous get filled which finally makes it not ridicously tedious.
In my opinion, even 3 seconds would be bad, as it is just flint, so please at the very least decrease it to 2 seconds even if you dont decrease energy cost, which would make it 140J/flint.
This is solely QOL, no money earnt, no resource exploited.
