We Really NEED a way to CONFIRM the request when someone wants to teleport to us. It's annoyng and causes defeats on fights. :(
So my idea is:
When a friend wants to teleport to another friend , the game should ask by a popup message "Do you want to allow X friend to teleport to you?".
OR AT LEAST when a friend wants to teleport and the other is on a fight WARN the person who wants to teleport with a message like "Your friend is fighting. Are you sure you want to teleport and join the fight?"
