All of this is really good info. I have Microsoft certs myself. The problem does fault to Bungie at times. When you are being connected half way across the world or South America (their internet is absolute garbage..not their fault) with P2P it's going to cause massive lag issues. The game needs dedicated servers if it's going to connect you to people across oceans and continents. P2P is an outdated server service. Get rid of it..solves alot of those problems ,too.
