OP enchants. After a while the game gets way too easy, when you have protection 5 diamond chestplate...
There is nothing to be afraid of it misleads the whole point of the game.
Oh and chunk load errors, it's funny how i have a quadcore i7, with gt650, and 8 GB of ram, and the game can't render more than 8 chunks away...
And if it can there are missing ones, or holes underground...
