There's a LOT of things that i hated about TNG+ combat that was irritating and made no sense, like how they stated every single thing they were doing while fighting in a SHUTTLE , i was watching some Voyager Eps on YouTube last eve to brush up on some ideas for my series and chakotay and Janeway are in a shuttle running from the Vidians, Janeway is Telling chakotay every evasive maneuver she is 'about to do" or she tells him every SINGLE time "Firing phasers". umm... that was the stupidest most unrealistic approach to stellar combat i can imagine..you don't need to EXPLAIN when your the frikkin captain, first off, and second, taking the time to verbalise every single action takes away drama of reflecting a desperate Chase or dog fight IMO.
I also hate how over dramatic they get with shield impacts and inconsistent strength rations of ship types..when small ships like a Bird of prey fire a torpedo at a Galaxy class starship, one hit should not ROCK and shake the bridge the way they make it. Now one other thing that boils down to not having a real explanation, i know it is because of FX decisions made on the part of the execs at the time a battle is shot and nothing more (although trek hardcore fans will come up with varied explanations, the truth is they do NOT think about the consistency when they do these things, they go with production effects and what will make it work for that moment.) Skin tight shields and Bubble shields...Enterprise era ships shields were using Fx akin to just above the hull shielding impacts, but then, so was NEMESIS with enterprise E, as well as Undiscovered country, and the new JJ trek.
When you see shields getting hit and they still say " damage to sensor array" or some crud, the only explanation is that shields absorb an X % of energy from a weapon and so much still penetrates, the shields still Hold but momentarily some penetration occurs, like internal bleeding from being hit by a blunt object i suppose. As far as the Bugships being wasted by defiant in one pulse phaser blast, i would chalk that up to wartime Race of studying ones enemy and technology and applying improvements to the weapons, the Defiant was after all, focused on being an anti-borg weapon like the soverighn was, which means IMO the weapons were made to be highly frequency mod capable and probably found a very effective setting that overtook Bugship shields faster than the Dominion were able to Compensate defense wise. (The Dominion may have been more advanced than starfleet, but we don't know that they were superior in EVERY aspect of technology, plus the founders assumed they had endless reenforcements in the Gamma quadrent and could chuck jem'hadar ships at the enemy and focus on offensive numbers vs researching technological superiority.) Wow i think i out ranted myself this time lol  :roll
