Right now on Balmung it's a 3.5 to 4 hour wait. That seems excessive for any game. The thing that worries me is that SE hasn't said anything about it other than "change servers or wait."

It's going to be like this for the next month+. Asking people to wait 4 hours to play a game seems problematic. Further, you can't really leave your computer during that 4 hours because you can DC from the queue, and if you get in and aren't around you get auto-kicked after 20min.
