Unplayable lags
From what I can tell its happening to a bunch of people. I am having the same problems though its much more then 5 seconds (so long I generally give up and log out when I see it won’t work immediately). I can’t help you fix it, though you can check latency (not sure how accurate it is though).
Log in to the world, and then minimize your game. (ALT + TAB works or the windows button, etc). From that open your resource manager. Go to the tab that says network connections. There should be a line that says Guild Wars 2, and a couple ip addresses and then your latency.
Hope this helps.
