Has there been any resolution to this thread/issue?

I only ask since it was opened in 2013, and we're having ongoing posts.... I'm not going to read through 220+ pages of backlogged posts though. I know I had a horrible of this problem back when the game was newer. It went away of it's own accord more or less, but seems to have started up again for me roughly a week before the "early access" of Heavensward began. Presently, on the rare occasions I do get past the 2002/5006/misc fun errors the game is basically unplayable for me, with a delay of four or five seconds on actions in combat. Chat seems to work well, for what that's worth.
