Game completely unplayable due to servers crashing and rolling back progress / loot almost non-stop.

Worst launch I've ever experienced. First time I've ever had to sit out most of the day. The crashes are so frequent it's just not possible to play anymore. Literally just now I logged back in after several hours of waiting for things to get better and right away the first zone I enter I lag like crazy and the realm goes down. After rejoining I can see that the server instance that I was in had disappeared so it's clearly nothing on my end.
