My idea as that there could be a second enchantment table that woulb be crafted like this

x=enchantment table

o=diamond block

v=redstone

b=book

o o o

v x v

b o b

(lol Bob heehee)

What it would do is make it so you can get high enchants without bookshelfs.Also the enchants don't cost NEARLY enough as a normal table. For example lvl 30 now is lvl 10

So hope you like the idea!!
