there are several reasons in fact :
1. this zone is not appropriate for gvg : can lead to confusion and the area might do that you back in the 2v2 zone in unexpected circumstances.
2. you need to add a no-add rule and some gm to monitor , otherwise what would be the point to do it
3. rps x2 is just meaningless to make ppl gvg, so i'm goin' to repeat myself you have to do something to make it worth abraxis
