Somebody in this threat argued that an unconscious person would not get a will save in the same way as a helpless person would not get a reflex save. This made me wonder what the PHB actually says about this, because in my memory it is exactly the other way around: a creature always gets a savingthrow unless he consciously decides not to take one.
Looking at page 133: Helpless defender, all it states is that the character has got an effective dexterity of 0 (-5 penalty to dex). It does not mention anything about any saves that will fail automatically. So I checked PHB page 150 and again I do not find anything to support this effect. In fact, the text in voluntarily giving up a saving throw suggests that it takes a conscious action to give up a save. The exception to this are harmless spells, where it takes a conscious action to make a save. Looking at page 119 also does not mention anything about saves not working when a person is unconscious. So there is absolutely no rule that I can find to support the opinion that helpless persons can only make fortitude saves. In fact, they can even make reflex saves. Which is not to strange since unconscious characters still tend to have reflexes.
As far as teleporting is concerned. The state of unconsciousness can be reached through more means then hit point reduction. In fact, a simple sleep spell will have the same effect. So if you allow unconscious people to be teleported against their will, you are opening a can of worms. In the end though I agree with people, that to treat unconscious people as objects is story wise probably the best descision.
