For those experiencing severe connection errors yesterday and today.
This is due to the cross server championship event.
The devs are aware of this issue.
They simply do not care to fix it.
They will blame your connection and your computer and run you through a series of hoops trying to prove it is your computer.
It is not your computer.
These connection issues occur every cross server event.
Especially during other events.
World Boss, Luxury, and Guild War.
If you like to help try to put a stop to this post a bug report about it.
Then screen shot your bug report and post the picture here.
