Thats the thing. It doesn't make much sense in a in game point of view.
I don't even have a problem with powerful monsters transferring some of their power to the weapons they wield, the problem is that not only monsters use this system but also NPCs like the level 6 veteran who suddenly doesn't benefit from having a superior weapon compared to a run of the mill sword. Does he also have a magical aura which imbues the weapon he wields?
I think the trouble is that you're thinking of the NPC as a "level 6 veteran". He's not a level 6 veteran. He's a guy with a +9 melee attack that does 1d8+4 damage who can use the "veteran's gambit" power once per encounter. Those abilities are not computed from class levels. They are just a set of modifiers that are appropriate for a level 6 challenge.
The challenge here is that, if you give him a +3 blade, he only gets a +2 benefit and you want to know why. If he starts out the encounter with the +3 blade, then maybe he never really did have a +9 melee attack with an ordinary sword. Maybe his "natural" ability is really +8? Or maybe, that warcaster behind him cast a buff on his sword? Or maybe, he really does have a featureless +1 sword, which is a particularly sucky magic item in 4E?
Personally, I might say that more powerful folks can get more out of a non-magical sword once they sharpen it themselves and have a bit of practice. So, IMG, if a 7th level character loses all his equipment, he can probably find a sword and squeeze a +1 (no special bump) bonus out of it. I'd figure that poor NPC soldiers use this as their bread-and-butter and that PCs could use it too, if they found themselves in a bad spot. Think of it as a martial ritual...
Of course, you may say, "that's all fine and good, but it's not RAW". To which all I can say is (A) we haven't seen the whole RAW and (B) even if it isn't (which to be fair, does seem likely), it's not a core scenario of 4E, so we'll have to look towards the commentaries, not towards the text of the RAW itself.
