frigid shoal
it's just flat number up
it would be better if it gave new behaviors to enemy stuff
ex. on hardest, enemy non-pierce gets pierce, piercing gets splash
so cannons would do extra splash, missiles would release a penetrator, lasers penetrate a bit, etc
this is basically the same thing as more damage but in a less boring way and that adds new threat
maybe something with splash or pen resist bonuses for armor instead of flat hp up, but that's harder to think of

i had an idea of on higher difficulties salvage may drop as the raw materials or part of the raw materials. stuff like steel wont be affected but reactors dropping 2-4 raw uranium may sting
processors dropping gold and coils may also sting quite a bit
i also imagine that difficulty rn is merely a placeholder and not the final difficulty. as this difficulty was probably a global number tweak and doesnt feature any complicated ideas or extreme changes

yeah change the eco difficulties too
