So i have managed to telefrag myself several times in GW2. I have noticed that by jumping while you enter an Asuran gate (sometimes) or when your character gets teleported from fractal to fractal you can actually spawn dead once you load into the new area
I have noticed this specifically while teleporting from the starting fractal “lobby” to the first fractal I did on that particular run which was the ocean fractal. I was dead when the game finished loading the ocean fractal. I was definitely jumping around prior to teleporting
I also noticed the same thing in Rata Sum. I was running around with my Asuran Mesmer and jumped through one of the Asura gates there only to spawn on the other side as a corpse
