I've never enjoyed the mechanic *unless* it has tactical implications, like needing to break armor or shields to hurt a heavy armor user, or sundering their weapon as a debuff. All of those things are currently served in other ways in the game. That said, I don't think I'm a fan of the current armor system, and if it transitioned to a more literal combat durability system where some weapons like hammers had anti armor capabilities, where things like swords were better suited to lightly armored opponents, I wouldn't mind at all.
But as far as just a simple resource sink, like needing to "fill your equipment up with gas" to keep using it? No, I don't think anyone has ever really enjoyed that.
