Id like to see more use of Scrapmetal reprocessing. Be wonderful if we can reprocess salvage (not just modules) down into even more base components. I use it round out any missing minerals I need. Altho, I imagine module reprocessing makes a bulk of minerals for null-sec.
Additionally if systems has alot of destruction happening in system, especially NPCs. It could spawn “Wreck sites” or “Debris Field” of a variety of ship hulls.
Then again there is always ninja salvaging or getting contracts from mission runners to salvage on their behalf.
