All constructs work like constructs, except Living ones. This is easy to remember. All undead are X, but skeletons are XY and vampires are XZ and shadows are XC but Wights are XZC is complex. But it makes a helluva lot more sense.

I'm currently concerned with fixing one thing and exactly one thing: types that have too much stuff in them and need to be broken down. More specifically, I'm thinking about rewriting Constructs, and that type has so much stuff in it that it's going to break into (at my analysis)
four subtypes.
Ability-subtracting subtypes may be relatively rare among undead, but they would be incredibly common among Constructs. Anything with distinct anatomy (I'm looking at you, Inevitables) should
not be immune to critical hits. Lots of things should "wind down" after a while (clockworks), and so they need con scores, they need to be vulnerable to fatigue and ability damage and so on. Lots of things have minds (nimblewrights, inevidrons), and so are vulnerable to mind-affecting. Lots of things have souls (warforged, robot girls), and so can be rezzed and are vulnerable to necromantic effects. Even more, a bunch of constructs have multiple of these: Nimblewrights wind down, they have brains, and they're vulnerable to crits. Inevidrons have brains and they're vulnerable to crits. Warforged and Robot Girls are constructs in nothing but name.
Additive subtypes take one less step to figure out. With subtractive subtypes, the process for determining vulnerabilty goes like this:
[*]vulnerable to mind affecting -> but wait! Undead type -> immune to mind affecting -> but wait! Dark Minded -> vulnerable to mind-affecting.
Not only is that's bass-ackwards relative to the rest of DND, it's two steps to think about. With additive subtypes, it looks more like this:
[*]vulnerable to mind affecting -> but wait! mindless -> immune to mind-affecting.
Needless to say, that's much, much easier.

I agree with Frank here. I've only played one 4e game, but I did like having a monster's combat role and basic properties described right in its declaration.
BTW: Koumei, if you're reading this, can I stick the Robot Girl and associated stuff in the Construct Operator's Manual (if it ever progresses beyond the concept stage, that is)?
