I was just wondering what the benefits were of being in a gang. I asked during the beta and was told it would be revealed when the full game released. The game is out (and loads of fun!), but I still have no clue what the point of being in a gang is. Do you get special stuff? If so, when? How do you get better reputation (mine seems to have been at 1 for quite awhile now)?

Also, how are the percentages gathered? Is it based on wins from people in that gang or something?
