It's almost as bad now as it was at release last year. It's taking the game sometimes 5-10 seconds just to recognize a simple command, and I'm doing that stupid thing where me and and NPC stand there swinging our weapons at each other for 20 seconds and nothing happens, then I get 6 pages of combat all at once, usually ending up with me pulling my items out of reclaim a minute later because I didn't know I had to heal myself.
Whatever you did to your network code, undo it. I can't play anymore until you fix it or I'll pull my hair out by the roots.
