Anyone else think that replica weapons should be storable in the Armoire?
It probably won't happen, because they're cheaply bought. A lot of stuff that you can get from the salvager/recompense NPCs isn't put on the armoire either for that reason

I don't change weaponry frequently enough to want to bother keeping replicas around (and I certainly don't have that kind of space), I just make a trip to North Shroud every time I need one.
