I am glad you are giving coal more use, but even as it, it could use some more uses. If you don't care about darksteel or magma (both kind of easy to pass up sets, truth be told), it just becomes inventory clutter. Magma ore might end up doing the same unless you give it some longer reaching uses than a passible pre-hardmode ore (magma furniture or nice looking blocks could be nice)
