I've said the same thing. Saves you an 8 minute game, or a challenge. Seems like a pretty good fix

It also gives some kind of meaning to duplicates too, maybe one for weapons and two for armor?

I'd say at minimum 2, chance at 3. I mean, it's 10% of an engram, and you can only get 1 IB item per gram. It's not going to make the grind any better, but it'll make at least some people feel a bit better about the 5 or 6 dupes they've gotten.
