It becomes especially noticeable when you and one other random are the only ones left on the team. Luckily most of the time I run with a crowd and they run heavy VSAT or get them in CP's.
So I guess if you want to clear a server out relatively quickly all you have to do is run VSAT. It just strikes me as effed that people will leave because of the eye in the sky.
Personally I am not sure if I would rather radar be always on or to get rid of radar capabilities altogether. Playing mostly HC I actually lean more toward getting rid of radar altogether.
