I would like it if the old repair system was brought back to work in harmony with the new one.

Dark matter shouldn't have completely replaced all previous repair materials, it should have been added alongside them as easier options to repair with, in many cases. However, in some cases dark matter is not as convenient to use.

Example: If repairing a Brass Ring, what's easier to acquire? A grade 2 dark matter or a brass nugget? The answer is the brass nugget, obviously. We should be able to have the freedom to choose what we want to use to repair stuffs.
