I'm not sure if this has been posted before but I think it would be a good idea to have an arhcheologist type character for all the constructs. The trade idea could be the same; that is, if you have all three drops from any specific construct you could trade all 3 items for new items if they become too damaged. It's the same idea as the Pboxes (if you have all top drops you can trade them all for all new gear if they become too damaged).
I know that they're doing this with the area K, why could it not be done with the constructs?
