Glad I'm not the only one. At first, it was only during instances. Every instance I did, one d/c. Worst one was for the final boss of Neverreap. I only actually did damage to it after 15%. I shut down my game, got back in, 2min load screen, and I was fine until my next instance. Then after my third, I was just doing FATEs. I quit for a few hours, came back, it was good until recently. I almost couldn't get back on this last time, and when I finally did, I immediately lagged out again.

Some of the times, I did get to the character selection, and it was blank. Then immediate d/c.

The weirdest part is that chat is fine. People are spawned, monsters being fought, and I can talk to people as I am struggling to keep connected. One of my runs was Praetorium, and we got to the back stretch to the second boss. Everyone just randomly stopped at the first arm you have to kill, and I couldn't attack it. So I asked if anyone else was having problems, and they said they were already at the boss. Yet I'm standing there a full minute behind.
