I'm not sure this a bug and not a feature since the full patch notes weren't exactly full patch notes. I had noticed that the blacksmith augments seemed to only working sporadically since this last patch. Before, if I crafted 2 of any metal item I was guaranteed 3. Now I have to craft 3 to get 4. Was the refined blacksmith augment reduced with this last patch? I haven't changed the minor card I'm using since the patch.
From my understanding the yield bonuses have been made to fully round down, in order to prevent issues such as a x1.6 bonus, craft 1 ingot get 2 ingots, because x1.6 would round up to 2, and thus create issues.
So the Refined yield bonuses, which are x1.4, would need 3x instances (2x instance being 1.4 + 1.4 = 2.8 = round down to 2, so with 3x instance being 1.4 + 1.4 + 1.4 = 4.2 = round down to 4).
I think its quite fair, honestly, to prevent unintended abuses, and makes you just need to batch craft to get the full yield bonuses as intended.
