Aside from the new recipes virtually everything else remains pointless to craft. None of the new recipes aside from a couple require any of the other crafting materials that were already in the game. So there is still no reason to salvage the rares you find.
It would have been nice to have a revamped crafting system. Something that gave you a reason to craft the recipes you already had. Something that would put those other essences, and not just the demonic essences to good use. Maybe certain recipes with scarce drop rates that gave us an option to add Attack Speed or Crit Dmg to a slot which could not normally roll that particular attribute.
This was just a lazy patch in my opinion. Most of the "fixes" that came with this patch should have been in the game from the beginning anyways. Such as the ability to retain NV stacks while switching acts. Or MP in the public games. And yes i know MP was not released with the game.
