Ok, i know i am necroing this thread but,
unless the spawning changes to being on a planet, salvaging is fine, though i feel that it is underpowered. Keep in mind that when more is added to this game, crafting will become more complex, and dangerous.
Salvage cannons are one of two ways players get resources. I would assume that all ships should have a salvage feature, and that big ships are big not so that they can be salvage ships, but that they can either be warships, transport ships, or planet crackers. I would assume that all ships are expected to have them. after all, everyone goes out in minecraft with a pickaxe, so why shouldn't all ships have salvage cannons?
In fact, i have a hunch that in the future, once mobs are implemented, planets will become too dangerous. so the survival noob strategy of buying a capsule refinery + faction block, and flying straight to the nearest planet and setting up a faction home there will no longer be viable.
Furthermore, with the new pirate stations just owning noob ships, salvaging may in fact be too underpowered, and may have to be enhanced in the future once nastier mobs get added to planets. I have already seen the threads on the steam forums complaining about this. The wiki tells people that they only need 80 shield capacitors for dealing with stations(it fails to even mention shield rechargers), so when they approach a pirate station and it kills them with one hit, they get very upset.
Though, i think that the main problem is the scanners. I find it super annoying that they do not tell me what each asteroid is. It is at the point now that if i want to build shields, i just find a planet, and ruin it completely with a salvage ship to get the crystals and ore required for shields, as blue asteroids are hard to find, and without shields i can not fly around without being instakilled by pirate stations. With the current pirate stations requiring a ship to have a minimum of 30k shields, they either need to change the spawn rate of all the asteroids to be more balanced, make salvage beams more powerful, or allow scanners to detect resource content of asteroids to help people figure out where the resources they need are.
