There is a few reasons why I dislike GM, mainly because I'm still old-school and dislike being told what to do by a robot, secondly because I generally know my own work area better than GM does and lastly because it makes us even lazier as we no longer need to use our brain to find a location, I find that if you find a location once by yourself then you will remember it but if you use GM then you will need it every time.
PS fer Horse, I also dislike bottled water, I have never bought a bottle of still water fer myself in my life.
