Don't really have an opinion on the Salvage armor (though I don't see how it could hurt, that said, they probably would need to implement a Kupon for it.) but I have to say, it is more than a little weird that the Frayed Pouches of Coins disappeared after campaign 10 and haven't returned. But we did go through a long stretch without the Empy +2 items.

I do think it is time for the Coin pouches to return though, they are a good option for many people.
