Note/Edit: I usually played SM "Always outnumbered (maximum 3 players faction) never outgunned."
OK, I do not mind the change as long as it does not take more effort to harvest the same amount of blocks in the same amount of time, just like what killed past servers. It's called optimization and it is always welcome. Farther, Higher, Faster, as Latins used to say. If now it is harder or impossible to do things (in a different, incomparable way, agreed) that were easy to do before, then the sandbox aspect of this game shrunk, see my signature.
Now just like then, it is important to deny the enemy any chance to recover resources from the tools he used to aggress you. In case you win, to make the entire adventure as high cost for him as possible while getting some proffit from it for yourself. While a torpedo salvo against the destroyed hull is faster in raising the enemy costs from "a few hits" to "no cube to recover from what I used in this fight" it still does nothing for your profits. So, then or now, salvage as much as you can as fast as you can from the dead ships is way more important than the possibility to mine asteroids or planets. If it takes too long, you are dead when his friends join in. And remember that what you salvage from an expired 100k warship are modules, advanced armor, things way more valuable than even the minerals they were made from. Things that shorten your way to the next improved dreadnought and lengthen the time until your enemy fills another BP and come annoying you again with his favourite dreadnought, because people never ever change and very rarely learn from their mistakes.
Automated planetary miners can do their boring job just as well if it takes them 1 hour or 1 week for an entire planet. Their efficiency is insignificant, no reason to talk about them here. But fast combat salvaging is a matter of (virtual) life or death, the way I see/play this game. So, are there any improvement in the time it takes to an efficient pow 2 salvaging array to harvest say, 40k mass to let you get the hell out of there before any more enemy dreadnoughts get to you, kill you and harvest you? For the same mass/volume of the old pow1 harvester chessboards, do the new harvesting systems have faster speeds on the same servers? Or is the pow2 a step backwards in this aspect of the game, too?
