Well, I wasn't the one that said the thing about Stormtroopers not being able to hit anything, that was the other guy. That being said, even in Andor (which I've watched) Stormtroopers die in a single hit, just about everyone does. I have no problem with Stormtroopers having decent marksman skills, but being able to take multiple blaster hits without going down is simply something that never happens. That also ties in to the overall subject of the thread, the instant kill. Whether they face heroic characters, trained soldiers, or armed civilians, Stormtroopers go down when shot one time with a blaster, simple as that. To have a Stormtrooper that doesn't go down after a single blaster hit simply doesn't line up at all with how Stormtroopers are portrayed anywhere in Star Wars media. As always, different strokes for different folks, but if I'm playing a game based on a particular IP, I want the mechanics to produce results that line up with what happens in the respective media.
The problem with this is the lack of hit points in Star Wars D6. If I implement a world where blaster bolts from basically any weapon are actually killing Stormtroopers on a single hit, then the overlap between armored stormtrooper's soak and a PC's soak is pretty strong. In the lore we don't see a lot of protagonists wearing armor, which is fine, we can explain via system mechanics why you might want to avoid heavy armor. But it then creates a world where if blaster bolts are one shotting armored stormtroopers they are very likely to be one shotting PCs as well.
So a solution to this is reframe what you think you are seeing on the screen. You see storm troopers hit by blaster bolts and go down, and it is implied that they died, but not actually said on the screen. We see no injuries usually. Just scorch marks on the armor. So what if the injuries are sub-lethal? In fact, there is a scene in "A New Hope" that seems to (perhaps by accident) validate this interpretation. During the scene where the Falcon is blasting off from Mos Eisley, several Stormtroopers go down, but then in the next shot as the Falcon blasts off, we see several of those downed troopers have stood up and are continuing fire. We could interpret this as a continuity error in the film making, or we could interpret this as stunned or injured soldiers getting back in the fight. After all, we rarely spend a lot of time with any particular stormtrooper. They are only on screen usually for a few seconds. Who is to say that after the heroes run off, half of the "dead" stormtroopers don't get back up, shaken and wounded, but not dead, calling for a medic or getting back into the fight.
That's the interpretation in use in my RPG, because otherwise, if a blaster rifle hitting a stormtrooper is invariably lethal it's going to be lethal pretty darn often to anything less than an armored Wookie.
And worse, if you don't use this interpretation, then you have villain decay and villain decay is lethal to a setting. If you have a "Cobra Commander" problem where the villains are always weak and self-destructing, it becomes impossible to convey any sense of danger and drama. Disney's "sequel" movies and later episodes of The Mandalorian had this problem at a severe level. Whereas something like Andor maintains an RPG like sense of scale, where Stormtroopers and Tie Fighters can be believably lethal and the Empire is shown competent enough that they feel like dangerous antagonists and we have to worry for the protagonists. The failings of the villains are believable enough and human enough that they don't feel exaggerated to "let" the heroes win. I'm not saying Andor's handling of everything is perfect. There are budget limitations that I think sometimes get in the way of presenting the scale of the threat, or the horrors of what is going on, but overall they do a good job.
The other thing to keep in mind is that at the time my campaign is set (now 14 BBY), the rebellion doesn't really exist outside of some disloyal politicians privately talking, some Separatist holdouts, and a few isolated cells like Saw's Partisans, the Ghorman Front, the Justice Action Network, etc. The PCs - Imperial Peacekeepers or "Bounty Hunters" - have been in more firefights where Stormtroopers or Imperial Troopers were allies than they have been in firefights where the Stormtroopers were the opposing side. Stormtroopers are often named NPCs more often than they are mooks. That's probably going to shift over time, as the PC's don't necessarily like the empire and take more illegal jobs from "rebel" groups, but right now Stormtroopers being one shotted just means they'd be both useless allies and useless enemies.
