we NEED Emerald Armor

If you want emerald armor, you need to come up with an effective explanation for how it contributes to the Minecraft experience and what its use would be.
Shoot your ideas at me. I've seen enough reviews from the Minecraft team to know their criteria.

gee how about Emerald Armor heals you, and no shit sherlock of course I need to tell people what it means or else it'll be useless and the reason I didn't put it is because this is supposed to be a meme, not something Mojang will see and say, "oh damn we should add Emerald Armor"

Just saying.
The stuff Minecraft fans ask to be added are like the things SSBU fans ask to be added.
