effect protection

Hey mojang!

Let's talk armor enchantments. They're pretty good. And the series of protections is pretty nice, too! Just there's one that would be really good to put in. Effect Protection (EP). Let me explain; Recently, I've been exploring snow biomes. The world I'm on has a really big one next to it. But, there's one problem; strays. I HATE strays. And witches! So what I'm saying is that there should be an armor enchant that, not completely takes out the effects, but lowers them. This would be pretty helpful, and seems to be quite simple as well for master coders like you guys.

A few more cool things you could do on it are:

-the higher the protection, the better the effect take away (EP II -2 potion effect, effect protection IV -4 potion effect)

-maybe make normal protection go up to five now (because you now have 4 main protections and I usually put one of each on my armor)

-make it add more to positive effects (strength II + EP III = strength V)

So obviously, this would be a good thing to add to Minecraft. Please add it! It would really fit.
