I must disagree that it is intended. If the button is called "Live Map," and it doesn't show the Dynamic Map, then that is somewhat along the lines of false advertisement, because all the other "Live Map" buttons show the Dynamic Map. It is advertising a live map, but the button does not give you one. If the Games server doesn't have a live map, they should delete the button.
True, but we should at least ask if this is fixable without breaking things. The Games server itself is relatively new, so some editing can be done to the Servers page. It would not surprise me though, if it is impossible to remove the button without hacking more things, and Aikar would rather make as few new hacks as possible, I believe...
