Was half tempted to come on and just write "magic" and be done.
Breakable armor is annoying yet convenient. I wish leather was unbreakable, I'd be fine with that, and diamond armor being breakable is kind of a huge thing. If it gets to post-game in OP mode and I'm with friends, I usually start to spam attack with an axe (trust me I'm aware that's not how it works) just to break diamond armor faster. Someone with full enchanted diamond on OP mode, they're basically unkillable 'till you break 3/4's of their armor pieces.
