Guild Wars 2

First and foremost apologize if this is the wrong section.
Me and my guildies, we do dungeon runs everyday and prior to today, all those runs were considered smooth (no lag issues, no DC’s, etc).
But today, after the patch (I don’t know whether its related or not but maybe it is), we found ourselves having spikes of lag, specially during fights, to the point where some of us even disconnect out of the game and its pretty much undoable as it is.
We were doing Ascalonian Catacombs.

had exacly the same problem here, and now i cant even play the game anymore
