I've been thinking about making a similar post since the game came out. The only thing this game lacks is a Private match feature. Bungie doesn't even have to do any of the work once they provide the feature. The community will take over and organize everything. Give us enough customization features to set the rules and just have Private matches give no exp, or credit for bounties and it wont be game breaking. Competitive communities make a game last way past its expected life cycle. Bungie should know how important giving teams the ability to compete against each other is. They made freaking Halo. I will tell you right now, once Crota fatigue set in I would have never stopped playing this game if I could run clan matches.
