Here is how you fix this problem:

First off, you got to be good at pvp. Good is not spam clicking, or trapping. Good is being able to time your hits. Chamber, you could never kill someone with 5-10 hits. It is imimpossible unless you attack someone with possibly iron or less. But in 1.9, Op Armor is as chamber stated, it is “unbreakable”. Well, axes pound armor. If you have enough strafe to pound their armor using an axe, your set. But, that’s my opinion on the best way to break armor. Now, there are always those trash pvp-ers that just are stacked… But that’s Piratecraft. The Eco has its ups and downs. Piratecraft trade is become useless, I agree.  Because of pvp, and enchants. But, Chamber, it all goes into a circle. You need diamonds for tools and enchantment tables, and enchantment table need bookshelves, which require leather, which requires cows. When there is no leather, there is none of this. The simplest thing changes the game. Without P4, what use is armor for? The satisfaction of knowing you have P4 is unexplainable. Minecraft 1.9 shouldn’t be tinkered with.

Thats is my opinion. Bai!
