being in Canada which is where the servers are and having the same issue pretty much shows this as not a distance from server problem. my ping is great most of the time. i always have Excellent connection listed to my world yet the moment i enter an instance with less than max players from my server I have additional lag if I do have all my server players the lag is about half of random groups add this to the .3 delay and tells can show to me at the point the servers have already counted down most of the cast bar yet on my screen the cast bar is full and the ground tell just appeared so I evade with lots of time left before the cast bar ends and wham get hit with the Damage.
