Neat bind-- I might have to test it out!
My only concern is with the camera settings... Usually when teleporting, I use a bind which has /camdist 300 in it, so I can actually teleport instead of just dimension door'ing.. If my camera view let's me see all around a building, I can TP to the other side of it directly, rather than up and over, like a ghetto flight power.
Isn't 30 ft kind of close?
