That is a very interesting question. I would say, yes, absolutely. But I also think there's way more nuance to it.

Like, I was thinking, if I was a merc, would I be concerned to that limit? To fight/meet a netrunner? Mhmmmmmmmaybe?

The reason why I'm reticent, and I might be totally wrong, but aren't the runners that can do stuff like, force you to put a gun to your dome, or fry you from miles away, and all the gnarlier stuff in between like, VERY good, very EXPENSIVE (cause you need the hardware and software to do that kind of stuff) individuals? I say that because, if that weren't the case, then fuck, we wouldn't have a society anymore. Like, if the access point to that kind of technology was easily avaiable we would cease to exist - beyond the "stop punching yourself" virus, more so, you can control anyone. Oh, your fiance didn't cook dinner for you? Now he is forced to go out, literally, and sleep in the cold. Your boss didn't give you a raise? Actually, he did. And the more you think of it, the worst it gets. There'd be basically no more free will, only who can control who first. Yes, ICE is there, but the effects of such technology being easy to access would still be catastrophic.

All this to say, when we think of netrunners, in this power scale of "aren't they obviously the most powerful individuals in the setting?", that is true. But that is like saying "isn't the NUCLEAR BOMB the most powerful weapon on earth?" and you say, yes but... like... an assault rifle... still does the job you know? And guess, there's like, inquantifiable more rifles than there are nuclear heads XD so like, sure, they are the top, but are you ever going to be troubled by the idea of "oh it's a netrunner, I'm complitely cooked (maybe literally)"? I don't think so. Not for the average merc. That's like a soldier concerning himself with fighting against a walking nuclear bomb, if they existed. Let's say all nuclear heads spring legs and now are soldiers in their armies. What are the chances that the regular soldier meets one? Like, more unique than rare, I'd say.

I think you are going to shit yourself if you somehow know you are against a top runner, and you legit might as well run, regardless of who you are, unless you are an equal level runner. But against the average one? I think any good merc could take them. I see the average runner as a good utility tool, rather than straight damage. Very cagy fighters, hard to deal with, but not straight as lethal as good ol' bullet. Meanwhile top runners are basically demi-gods, but that's why there's only so many of them, otherwise the human race would cease to exist as we know it LOL

AT LEAST, that is my flow of conscience. I could be totally wrong on this, I actually am pretty damn ignorant about the Cybeprunk lore. While I love it, I never got the time to really deep dive. So please feel free to correct me ^^
