I have been having issues as well.Please be aware that ping (your connection to the server) is ENTIRELY different than you data transfer between you and said server.After utilizing wireshark tests,it has been proven that Time Warner Cable is setting data transfer for this game at the lowest possible setting during heavy traffic times.In atleast a portion of these cases,people's ISPs are indeed part of the issue.

As a healer,dungeons were a nightmare with the screen freezes of 1-5 seconds at a time.My fix?A VPN such as WtFast will most likely help you.My dungeons were seamless after I started using it.Setup time is only a few minutes and there is currently a free 30 day trial.This is only a temporary fix if you want to avoid the 9.99 a month fee,but hopefully the issues can be worked out within the next 30 days.Have fun!
