    AC is more than a dex save… And in fact may not involve dex at all if the target is wearing heavy armor.

    It’s a very consistent system. Direct, targeted attacks with a physical manifestation (that is, some kind of targeted projectile or weapon swing) roll against the target’s general-purpose defense stat (AC). Indirect attacks (e.g, fireball) or things that are otherwise simply “happening” to the target has the target rolling a save of some sort to resist the effects somehow (dodge out of the way, resist mental influence, hold themselves upright, etc.). There’s nothing arbitrary about it, and a unified defense system would no doubt involve a lot of special-casing/ad-hoc calculations to be at all worthwhile, to the point at which it would be far more cumbersome and confusing.

    Let’s say we only use AC as a defense and have no saves. How does a spell like Hold Person work? Does the target use their wisdom modifer instead of their dex modifer for calculating AC? Does the armor they’re wearing affect their defense against it? What about proficiencies or other bonuses? Since the target is no longer making a roll, how do buffs to protect against the effect (e.g, bardic inspiration) work? I don’t think there’s a way to do it that is not more convoluted.

    Skill checks don’t really overlap at all, other than the fact that they use the player’s attributes, I guess.

      I’m well aware. I just said that Dex is represented twice, once in each “system”.

      There’s nothing arbitrary about it

      I mean the division itself is entirely arbitrary.

      a unified defense system would no doubt involve a lot of special-casing/ad-hoc calculations to be at all worthwhile, to the point at which it would be far more cumbersome and confusing.

      What? No? Why would that be the case?

      The two systems could be mostly merged by just having saves be passive, and having the attacker roll to overcome them. Exactly like AC currently works now.

      Let’s say we only use AC as a defense and have no saves. How does a spell like Hold Person work?

      The caster rolls their spell attack against the target’s Wisdom defence/save. Exactly like how AC works now for physical attacks.

      Buffs like could add a flat value to the defence stat, like AC buffs currently do.

      The more I think about it, this would actually streamline combat a bit too. Because the “acting” party is doing all the rolling, rather than waiting for the defending party to roll a save to see if attacker gets to continue.

      Are you going to reinvent 4e? Because a lot of attempts to fix 5e turn into 4e.

      I think it worked like Everyone has a few defenses. Probably Armor, reflex, will, fortitude. Write them down on your sheet. They can receive bonuses from different things. All attacks target one (or more, maybe, if you want to get fancy) defense. Attacker always rolls. Easy peasy.

        I wasn’t trying to fix 5e, merely demonstrate the futility of it.
