Been feeling the same way. Have been going back and forth with technical support as they try to see if the lag is due to my internet, even so far as to use my cell phone as a wifi hotspot and play using that connection instead of my wired internet. I have spoken to my ISP numerous times and they can't find anything on their end that is contributing to the performance issues that I experience in the game. This is the only Online game where pressing a button doesn't mean it's going to register in game and animations stop halfway with nothing happening.
