Who that can be nice is add the possiblity to choice if player can teleport on you or not, must be possible 'cause we can't in non-unique account, cause well ... I was with my lvl20 Rogue against 2 Medusa, using my invisibility to kill then as close as possible, then a lvl3 teleport on me (certainly to leech some exp), and then 2 Medusa focus him ... just behind me ! Quickly dead, no time to F5, so maaad.
