I just bought an Xbox One yesterday and have been a Halo fan all of my life. However, I don't know what's frustrating me more. The fact the 343i's servers disconnect me from a game so quickly (without a 10 second chance/black screen) to reconnect), or me being in a college dorm with a Strict NAT type and not being able to change that. This sucks cause I love to play Halo competitively. After my first 10 games of Halo 5, I achieved a Gold 4 rank in Halo 5 doubles. But now I'm banned because of my unintentional disconnects. My question to 343i: Is it the Service lobby's fault or my Strict NAT type's fault for disconnecting from 1 out of every 2 games I play? And how can I fix this so I don't get permanently banned?
