I suggest that when selecting teleport to home capitol, we get a screen that says: Are you sure you want to teleport?---Yes, No.
Teleporting is as much of a major decision as , for example, leave battle. This could replace the count down or be added to it.
So far, I have been accidentally teleported back to home twice, although on the last one, I did not see a count down. Hope this is the right place to post this.
