Same here! Somebody said that it might be because of the addons (arc dps and mount radial). I deleted every addon, deleted and uninstalled everything about GW, and reinstalled again. Same thing.
This confirms its not my fault and they really broke something with this new patch. I do get kicked off to char select after not being able to move or use skills, even tho I'm present there and get event participation or stuff like this, every 5 minutes. Even if I'm alone same thing happens.
Weird thing to mention, the highest ping it showed me I had was around 50. But acting like 5000.
So what do we do Anet, eh?
