The Gladius *needs* the IR Pulse Laser to be flux throttled to balance. This setup gives it a good initial burst of damage that then tapers off. Many modded fighters also do similar balance tricks.
I'm not convinced that an unthrottled Gladius would be overpowered, but perhaps that's just because they've performed so poorly for me thus far. (I've about sworn off the Gladius as-is, Vanilla or otherwise)
Granted, what *I* think would happen may not be what actually happens. Hearsay is no way to balance a game. I did manage to make a "mod" during my recent dabbling that didn't immediately crash, so maybe I'll make a pseudo-Gladius for testing with that flux-free hullmod. See if that performs fine for its costs, needs a slight OP increase, or murders everything so badly it absolutely needs its throttle back on (which I highly doubt).
Interesting about the mod fighters using similar tricks. I've been using quite a few mods on my current playthrough, and I just haven't noticed. Maybe I've somehow avoided the fighters that use that specific method of balancing, or the ones that I use aren't quite an extreme case as the Gladius? Not that I've been scrutinizing them super closely, as the ones I've used are getting the job done. (I can't say the same about the Gladius, unfortunately)
Well, the flux thing is good to know in general. I'm considering making a small Vanilla+ style expansion mod, and a decent chunk of the fighter ideas I had would, uhh, not work. It's good to discover that now rather than well down the line.
Anyways, I'll try to test a flux-less Gladius soon-ish. I'll let y'all know if that ends up changing my opinion on that bird.
