Suggestion Protection IV Armor: Taken Out?

[Dsawemd]

Trying to think outside the box here: I wonder if there would be a way to limit Prot 3 & 4 armor to tank classes (thinking Paladin atm). That might be a nice way to keep it in the game, allow for some sort of economy with regard to the enchantment of armor, and give pallys a perk (perhaps balance their ability to wear better armor with some sort of reduced damage output).

Good thinking out of the box! Keep it up!
But
With how strong prot IV is right now, if it were restricted to certain classes those classes would require additional balancing.

In particular I bristle to the idea of "giving pally a perk" as they are currently the most popular and competitive warrior class.
