Apparently I'm the first one with a SW badge to feel like commenting on this
I haven't read the fic yet, I plan to though. However, comments like beams pierce shields just sound incredibly stupid to apply to SW. Sure, a beam generated by a massive capital ship powerplant in any universe is probably capable of ripping through a measly fighter's shielding. However, FS capships don't even have shields, and their armor alone can take quite a few beam shots. I think it's safe to say that any capship with an energy shield, would be significantly stronger than that which could be equipped on snub fighters. Using the Death Star as a reference for a beam piercing a shield is equally ludicrous, to assume that FS ship beams are anything close to a beam which can detonate a planet means that any FS cruiser should have the destructive power of 10 Lucifers. So, for the majority of capship beams, I have to imagine that a large Star Wars ship could absorb quite a bit in the shields, from the entirety of a smaller beam to a good chunk of the biggest beams. I do understand they wouldn't be invulnerable, and that a good pounding should inflict severe hull damage to even an ISD or MC80. The only other thing then, is how quickly could 100 dual/quad turbolasers melt through a FS destroyer's hull? Without shields, a constant barrage of turbolasers would make fairly quick work of even an Orion or a Hecate, disregarding the pounding the SW ship would be getting from the beams in the process. All in all, I think it should be a fairly close fight, and that a captain's tactics would be the deciding factor in a fight. I don't think either one has an insurmountable technological edge over the other. It's probably much closer than Ori vs Jaffa
