If it's peer to peer then "Netcode or destiny servers" will have little to do with lag issues. It's more about the matchmaking to ensure that the spread of pings to a host is within "reasonable" and that the average ping of the remote connections is low enough that the host doesn't get host advantage. Lot's of statistics to balance, lots of upper and lower limit definitions to play with. (call this "netcode" if you want, but its a meaningless word) I feel that the problems at the moment are mainly caused by 2 things: The spread of acceptable pings is too high (this leads to whole teams of low pings vs high pings - high pings win every time because lag) The number of outliers allowed is too high (ie, if 91.66% of a server has a low ping a single high ping player will be allowed in because their ping doesn't get filtered out as unacceptable, this player gains a massive advantage) TL;DR - it's not "netcode" it's filtering where too high a bandwidth is being allowed in the matchmaking algorithms. This could be fixed by reducing the filter bandwidth HOWEVER this may be something that is predetermined by the console manufacturers and completely out of the control of Destiny. (because Sony & MS both want even people with crappy pings to be able to "enjoy the same experience" as people who actually pay for decent internet, and in this case this means that they would have to throttle back on the game speed for the rest of us (ie, introduce artificial or input lag) in order to make it less noticeable to the players with decent networks)
