How do you use them?
Let's say there's Graviton Beam for suppression, but in reality a pulse laser or mining blaster does the exact same job, but they generate hard flux on top of that. The range feels useless if it's the only thing firing, its damage on armor is negligible enough to turn off shields, vent and go back in.
Then, there's the tachyon lance with insane damage on paper, but again, the shields just brush it off as if it was a soft breeze of wind.
"But if it doesn't hit the shields it's devastating!" Yeah, just like a plasma cannon, autopulse laser, etc.
And the worst thing of all is that they can be fired even with minimal amount of flux remaining, which means the two mining blasters next to it never get the chance to shoot again until the AI backs off for a full vent.
From what I've seen the only times when they are able to kill is when the battle is already won. Good job on cutting up that cruiser... surrounded by 4 other ships.
