Everyone in the server have experence the LAG in the server.
everything is unplayable.
Which map IP?
Not sure. They will address it I'm sure. Remember Anet is in Washington State which is on stay home orders so they dont have a normal staffing situation at all. Just hang in there.
The server of Gw2 are not hosted by ArenaNet nor in Seattle. They are Amazon-Server. Some people do have lags and some (like myself) don't. First of all, even if a GM was online, he wouldn't be able to snapp with his fingers to fix your issue. Also, putting all your title in CAPS is rude and childish. This just makes people (like myself) think that it isn't even worth reading your post, still hoping for a downvote button btw.

Its a thing since last years World boss-event (or so). When they changed their servers, it got terrible,but not unplayable.
FYI, the servers were changed long ago, way before last year's World Boss Events.
