That alternate and separate remnant cruiser I mentioned about, the one I modified into a visually symmetrical super-ship for my own use. Well, I'm still quite baffled that for once I didn't/don't even have to make and put alternate modified weapons on it because the default two Heavy Blasters and the default two Mjolnirs do the most damage, not sure about the default two Ion Cannons I have on it but that aside, what makes it all work is the fact that I made that personalized ship of mine get rid of flux in much larger amounts.
Heh, I'm such a hipster minor/robust modding nerd of sorts as half the things I usually use and play with are usually all altered and made superior by myself and so running into something that already has the destructive effect I need is just plain awesome. Modding and cheating is the first thing I do in every (singleplayer) game.
That also aside, currently I'm flying a heavily altered and personalized version of a Talus-class carrier freighter from Tore Up Plenty mod with more visible engines on the right bottom side which I added only to the altered version to calm my OCD down about trying to figure out where the center of mass is while using thrust to go forward in-game.
By default, Talus and its precursor, Tarsus are not combat ships, I know that but for me to be able to use and enjoy ships with small weapon mounts only, I do need my customized super weaponry on the weapon mounts that are set to universal so I can test other weapons in the game and make sure I'm not missing something new I could put to use but that is a secondary function only, I prefer to keep my options open just in-case and my weaponry quite deadly.
So why am I blithering about off-topic stuff? Because no matter what majority says, I still get enjoyment when I take down a large ship or a derelict mothership or a remnant battle station, knowing full-well that I'm gonna win the battle, gives me the opportunity to zone out, relax, chill and ponder on the game's lore and sometimes my god-like character's backstory and history.
To avoid further derailment, I find the remnant Spark fighter wings quite useful, those shields they have are indeed what helps them to survive, though I don't pay much attention to where they fly and fight as I'm too busy piloting my main ship but I always tend to find them drawing most of the enemy fleet's attention and buzzing around the bigger ships basically trolling the heck out of the opponents like keeping them trying to point and shoot to no avail and seldom see one or two of the Sparks coming to my ship for repairs. I'm not much of a fighter fan though and so the Sparks I've used have default configs of .8 version of the game.
