But then you can't see how many AP's you need to go up a rank or who the person is in front of you. And there could be a small pop up that comes up with all the people on and loads of pages. Like on tanktrouble.com
Allow me to be frank: People are morons and will spam and harass the nearest users above their rank. At least with the top 100 the permanent ban or the 1000+ deleted posts and comments will hurt like hell if they do.
