I had a random disconnect in ROM just the other day. Pretty long one, too, could not get back online for almost 7 days. Turned out the source was a power outage in my area. Who knew ROM needed that?
In game... the usual. Crashes once in a while, but no unexpected disconnects. May they be caused by the game activity or location perhaps, or other networking on the PC, or are they truly random?

Oh, and people who have more than 3 classes are clinically insane.
