I don't think you'd have made much. Because if you stuck your retainer in the ward that sells shields, no one would go there looking for helmets, pants or gloves. Other people would be making those millions on helmets, pants and gloves in other wards while you wait for the shields to sell.
Since you're only able to sell shields, you may as well put ten up. But of course they're going to sell slow because there's now ten to get rid of rather than 2-3. Normally it's far more efficient to have two shields, helmets, pants and gloves on your retainer and restock each product as they sell.
Of course the changes mean you can't do this any more and you will have to get used to sticking ten shields on your retainer and keeping your helmets, pants and gloves waiting until all those shields go so you can move it elsewhere. But then, you want to sell more shields? Tough, you're selling helmets now so you can't.
I make money from multiple crafts, or at least used to. Now I've got to pick one item and sell nothing but that. The idea of moving a retainer around when shit sells doesn't work, because normally when shit sells you make another and restock.
Anyone who thinks this system is better isn't thinking right or doesn't craft.
