It would be tough to make it non-abusable. Perhaps something like.. you type in 'lost' and then if you don't move or enter combat for 10 minutes it will trans you to TS or something like that. For when people are truly lost on the map or a bug makes them stuck. If it takes 10 minutes it would be much harder to abuse.
If you say plz because it is shorter than please, then I will say no because it is shorter then yes.
I like the idea. I think 10 minutes is fine too, who would want to wait 10 minutes what it's so much easier to walk places. I think it would avoid abuse by most people. Except maybe idling tinkers... Should people be able to do LTs with this Lost command?
I am not sure... Well, obviously the command shouldn't work if you are in a castle. though people have been known to log into bugged castles... And then there are trapping people... Trans runes to the demi dragon or Anarex. Shouldn't work for that either.
Make it check if you are in a real no-exit room maybe...?
Modified pocket dimension so that if you fumble, you are stuck for 10 times the normal duration for the power you cast it at. Teleporting out is still an option if you have the ability, otherwise you will get booted when it expires.
