I’ve been having this issue since the removal of the wintersday events in a patch recently. At a certain time on NA I will end up rubberbanding a lot, very delayed ability activation, attunement/weapon swapping and salvaging all take 3 seconds between click and act.
Usually this is nearly instant depending on my internet usage. I was just under the impression that Gw2 just hated me because other games work just fine at this time and had just given up on the late night gaming dream, but I got a cousin to log into his EU Gw2 account during the laggy time of day and it worked fine, just as well as NA would before this patch. I just want to play the game on my account before I go to bed.
I live in New Zealand.
