Town killing Warning
 

There is a new, confirmed method for townkilling that works for Assassins only, on the realms. You'll want to be very careful about any Assassins who are standing just outside of town, since that's the place they have to be to kill you. Stay off the screen and leave town by waypoints and you can avoid this. Blizzard knows about the bug and will hopefully patch it shortly.
