Please point to anywhere in the show where Nanoha made a shot from 4 miles away. No, seriously. I'll wait.
As I recall, the longest attack we saw that made by a mage was Hayate backed by the processing and possibly energy capabilities of the Long Arch.
Fuck, see I didn't want things to go this way because its going to progress from me simply asking some questions to me looking like a dick when all I wanted was some clarification so I could plan better.
It actually doesn't matter anymore because we don't
need to shoot from four miles away. We can have Sam get the mage alone, then close the distance and start wrecking the Dragon Slayers, especially since it was stated that we won't be sucked into the field if we do this.
But since you asked, episode three looks like a very nice distance of at least a mile maybe 1.5 miles after comparing the different views of the tree Nanoha sealed. And that's just the first season. A mile isn't as long a distance as a lot of people think. I run a mile and a half for PT in the military. The longest sniper shot in history was made by a McMilan Tac-50 in 2017 by a military sniper. It was shot from 3,540 meters away, which is 2.199654 miles. I'd expect a piece of alien tech as advanced as Rising Heart (and thus also Perfect Storm) to be able to double a simple earth gun. Especially since it needs to be able to be used in space, as they are a spacefaring nation that engages in space warfare. And in space, range is certainly key. As it is, you are saying that Nanoha can be taken out by a simple unpowered human with a sniper rifle, since her range is less than the rifle's by a quarter.
That being said, you're the DM in the whole thing. If you say the range is too far, then fine. I was presenting arguments for it because it
wasn't the DM who was limiting the range before, just another user. There's a reason I ask questions. Because until the DM says no, anything is possible. I've done lots of D&D and you have no idea how many times the DM straight up said they would have allowed my idea if the party had simply asked, but the rest of the party
assumed the DM would say no. I generally ask rather than limit myself.
If you notice, once
you said no I stopped trying to justify it, and instead said we needed to find a way to increase our range in the future. Until this post, again
because you asked me to try. The only other thing I asked was if we could modify the RF so that it was
smaller than 4 miles, so that the strategy would still be viable. I don't think I got an answer on that particular modification either though.
