Okay, I get what you're saying, but I would have to disagree that it's so difficult to find a spot that you know you can safely log out in.
Additionally, creating a delay is essentially the same thing as creating a dungeon log script-so you're really just making a fail safe. I don't think that redundant systems are efficient or useful for the purposes of this game. If something doesn't work how it's supposed to and there are severe, negative consequences for it, you can always appeal to the CC or a DM. But these cases are fairly rare. We've probably all had them happen to us, but how often? It sucks, yes, but it's much more managable imo to deal with on a case by case basis than to creates far more opportunity for exploitation than it does prevent cases of I guess.. wrongful death? Or whatever you wanna call it. And lets not forget, there's no overriding reason your character should be ported out of a dungeon if they log there other than ooc convenience-they didn't leave, so if it doesn't work you could also take it in stride ic as well. It won't be the end of you, it might suck and set you back a little as I said, but it's nothing world shattering.
