Why does it seem that in major engagements, our brave heros, or their blood enemies, decide to fight with no shields on? The assault on DS9, none of the Cardassian or Dominion ships had their shields on. The First Battle of Chin'Toka, Klingon and Federation ships ripped to shreds by Cardassian orbital weapons because of no shields. The list goes on, I'm just too lazy to remember specifics. Did they decide that they're going to die anyway so they'd rather not prolong the fight? I would understand if their was maybe a budget constraint but the SFX for shields can't be that expensive. And if the shields were just absolutely, 100% ineffective against all weapons then it seems like it would be more prudent to not include shields at all and just have ships with 5m thick hulls like conventional armor. Thoughts?
