QwerTech doesn’t have the same performance Issues that the vanilla Crafting Table has. That is why I removed the Crafting Recipes involving a Hammer when QwerTech was installed in order for less overhead in removing and adding Recipes back again.
But now that I have my own Anvil, I basically dont have to rely on QwerTech to reduce the amount of Vanilla Crafting Recipes and can remove a ton of my own Recipes permanently in favor of my Anvil.
