That must mean you were fighting a not-fully-operational battlestation. Normally they have 3 shield segments, projected by a module in the center of each of the flat segments. Only the corners stick out of the shield. Shields have capitol ship level flux and each one is independant, so when it spins around behind it gets a chance to take the shield down and vent unless you are surrounding the station.
It IS possible to take down their "protected" modules without killing the shield, but you have to angle the shot in the very narrow gap between the corner and the shield.
You aren't taking any big fights then. That's not really surprising with your game plan, but it's not a universal thing. I'm always trying to take the biggest fleets I can, and even individually large enemy fleets can take too long for my phase frigates and I have to pull them out. Keep in mind I have a Paragon, Astral (both deployed together) and all the other high tech ships I want as well, plus some support carriers.
A big single enemy fleet can consist of 2-4 capitol ships, 3-7 cruisers, 4-10 destroyers, and more frigates than I'd care to count. I also like to round up multiple fleets at once, sometimes for challenge but sometimes because it's cheaper in terms of supply/CR (and time) to kill them all in one deployment.
Also, every frigate I have has hardened subsystems, and are usually piloted by officers with combat endurance as well, and even those tend to hit reduced CR in a lot of my fights. If I can't win by the time my Tempests are malfunctioning, I'm up shit creek without a paddle.
That leads me to the High Intensity Lasers part:
I can NOT afford to have my few Big Guns spent harassing. Basically, other than my Paragon's main weapons and my Astral's bombing runs, I don't have anything to flux out larger ship shields. A swarm of Tempests/Shades with Heron support just isn't going to do it, and I need to break through as quickly as possible, so no time to play stand off.
One thing I've been known to do is run the paragon with shields down, all weapons off (so 0 flux), charge straight up the middle and wait until I can get a cruiser+ fully into my Plasma Cannon range, then unleash holy hell on it. If I can't kill it in a single flux pool I'll even vent right there in its face and do it again. Odds are the Tachyon Lances have disabled its main guns or its own flux levels will be so high it can't risk firing, while my frigates and fighters are keeping everything smaller occupied (and picking them off left and right, naturally). Even Onslaughts tend to get locked down by this and die extremely quickly.
