Normally when flying around my pings are between 100-200 with spikes up to 600 every now and then. However, when I get into combat with a full group and many enemies my pings skyrocket... 1000s if I'm still back a ways, up to 6000 when in the thick of things.
This is true whether I'm running at max graphics or min graphics and different screen resolutions. I'm running an OC'd i5-750, single Radeon 5770, newest drivers, Win7 64 Pro, and have 5Mb dsl.
Is anyone else experiencing these issues, or have ideas on other things I can try?
