I know this subject has been brought up before, but I think it would be nice if instead limiting everyone from teleporting to you, you could select who can and can't. So many times, I have lost or my experience points were reduced, because someone teleported to me during a fight without asking if I wanted them to. I have lost battles because of this as well, expecially when you have an inexperience wizard who is just exploring or hitching a ride so they don't have to do the work. It becomes annoying, especially when you don't want or need the help, but in the cases where you do, you would like to have someone come to you.
At least be able to turn it on and off during the match, so you can call for help when you need it.
