Maybe fun for people who just wish to be annoying. Its not fun when you are sitting around and having a talk with some friends, all of the sudden some douchbag comes over and ruin it. Problem here is, you can't go outside the city, because they will just kill you again.
For people who just started playing, they get a bad idea of the game and the players. For my sake i hope they will remake the Confusion so they just spin around and can't attack or something.
