Anvil Cost Gets affected by the Result not the Input

Greenjab came up with a new too expensive machanic that generates the price of a combination/edit of item(s) by considering the result. Not the items you put in.

   Here is an example

So if you combine 16 Sharpness 1 swords to create a Sharpness 5 sword and you combine it with a Unbreaking 3 book. It will cost the same as if you had applyed a Sharpness 5 book straight from a villager on a sword and put a unbreaking 3 book on the sword. (Obviously the cost to create the sharpness 5 sword from sixteen sharpness 1 books is more expensive then using the villager's book but it is alot better then before.)

Which allows for your progression to be more gradual. Pretty nice right? Also, this system allows for repairing to be done indefinately without the cost going up. (Unless you add more enchants to the item of course.)  He does a lot more to make enchanting and Minecraft in general a lot better in his mod. (In my opinion, because some of the changes he made are pretty controversal.) If you are interested in stuff like this, please check out this guy's channel, @GreenJab. (On YouTube.)
