One thing that I was always a bit annoyed about was if I visited Cthulhu. It isn't because of the effects while you are alive, but how the effects continue on after your death.
People that were "Cthulhu'd" still should be able to have conversations with the other dead players. Instead, you are still stuck with the scrambled text. I know it isn't impossible to talk while Cthulhu'd, but it makes it near impossible to carry on conversations.
