Who remembers the level 50 enchants? well, i think they should be brought back into the game. not normally, but through a more expensive, higher tier enchantment table. this way you could get stuff like sharpness 6 normally but it would cost maybe up to 60 levels. i think this would add some more fun to the game because lets face it, who doesn't like OP swords and tools? this could become balanced by making this the recipe:
X= Enchant table D=Diamond B=Book

D D D
D B D
X X X

If you like this idea, please diamond this post.
