Even without having canonically mentioned a Borg-inspired tech, at full strength, and even after having been captured and inactive for 25 years, she single-handedly wiped out 47 Klingon ships upon escaping Rura Penthe, following up with the destruction of an entire armada of Starfleet capital ships at the Laurentian system without breaking a sweat.
The ships at Laurentius were never touched by Nero. There was no Rura Penthe in the movie, no capture, no dormancy. And whether Nero really defeated 47 Klingon ships or not is debatable - it's all hearsay that oh so
conveniently appears to draw Starfleet's attention elsewhere, supposedly to Laurentius...
The Vengeance was designed with loads of weapons which never made it to the screen.
One then has to ask why Marcus didn't use these weapons to more quickly finish off the
Enterprise. Why go easy and delay? There was nothing of value aboard the
Enterprise that Marcus knew of, and it was imperative for him to kill Khan and to stop Kirk from blowing the whistle.
The mind-meld scene was heavily re-edited.
Thankfully so, as the aired product is superior to the original plans, both in terms of dramatic pacing and of story logic...
The comic reflects the original plan, where Romulus was destroyed prior to Spock even launched.
Which makes it strange that Spock should launch at all. If he's late from the farewell party of Romulus, the next one won't happen until a few years later when the supernova reaches the next star system of interest - so why the hurry?
The way it's edited allows us to believe in a realistic supernova whose only immediate impact would be to pulverize Romulus (thereby upsetting galactic balance and triggering horrible wars and whatnot). Heck, the way it is
filmed not only allows but begs us to believe in such realism, as we see in the zoom-in that the star that blows up is right next to planet Romulus.
In any case, the fractured mind-meld visuals give plenty of wiggle room.
True enough. But if we wiggle too much, we'll have to start pretending that Spock flat out lied to Kirk, as he also gives a narrative. And that narrative does not allow for passage of time or space between the loss of Romulus and the timehole trip.
Yup, a Galaxy class starship could fire enough phaser and photon weaponry into any area of space not much could survive, according to Timo, so just massive gross incompetance from every single person in charge on that ship.
Every starship, starting at least with TOS but probably with ENT, has been able to deliver enough firepower to level multiple cities in a short timeframe. By the time of DS9, this has been upped to a fleet of a few dozen such ships melting the entire surface of a planet in a matter of minutes. So it directly follows that shields are very potent defenses...
That accepted, we can talk shop. BoPs are weak ships by the frequent admission of their own crews, but is that offensively or defensively? Outside the Dominion War, such ships are only lost when caught shields down, which tells us little. In the Dominion War, and in the "Way of the Warrior" preceding it, single shots from fixed installations (surface bases, stations) can kill small BoPs even when they have little reason to be unshielded. So multiple hits from the E-D
ought to have an effect even if single ones may well be weaker than their "ground fire" equivalents.
Yet the Duras sisters themselves appear overtly surprised that their shields are holding. We see Soran promising the sisters some means of defeating the odds, that is, the E-D. We never hear what those means are. One of them evidently is the bugging of the VISOR, but it should be within Soran's means to bolster the shields of the BoP, too - after all, he comes from a senior culture and has demonstrated technological skills beyond those of the UFP (might also explain why the heroes have such hard time noticing the VISOR-tapping, as opposed to, say, "Mind's Eye" which already sets the challenge level rather high).
In general terms,
Galaxy class vessels are curiously distinct in being the only Dominion War participants on the Alpha Axis to actually score capital ship kills (or indeed any onscreen kills at all,
Defiant and
Rotarran victories notwithstanding). They are also the only type not shown taking damage or being destroyed.
