From my limited look at it, it seems to be fixed, and there was something in the patch notes about correcting the damage buff duration. (There were other problems with /nin than just the damage, but I haven't been tracking the issue very closely.)
And for a while things were cold,
They were scared down in their holes
The forest that once was green
Was colored black by those killing machines

I was thinking of adding in a custom boss with the /Nin power set to my upcoming arc because I wanted them to use stealth, but I recall that early on, people were saying the set was quacked because a foe with it got the +crit on every attack they made, stealthed or not.
Has that been fixed? Is it safe?

I have tried it several times and the /Ninja LTs no longer seem to be able to one-shot scrappers. The same seems to be be true with bosses.
I'd suggest making your boss and trying several different characters against it in test mode.
