Everything was working perfectly fine for me, never had any disconnects, ever. Raised 5x Mages all the way to 80.

In the last few days however, I too have been seeing random disconnects, and often. Very annoying.

Perhaps it has something to do with running two copies of WoW on the same PC?
Maybe blizzard changed something in the patch that now causes this problem when running multiple copies on the same PC at once?
