Can anyone explain to me why I can run the citadel gate from 19-27 without any lag, then go play with a guildmate on the same gate right afterwards, and have debilitating lag and disconnects immediately when I join on 19? Nobody else on my network was doing anything on either of the two runs.
I would rather just have lag all the time than be teased with flawless gameplay 50% of the time, and then not be able to play the other 50%...
Try checking your upload speeds during the lag, it might be saturating your connection. If so, it might be caused by the following issue:

The evidence is mounting this is some kind of bug in the game's netcode...
