I have 5 computers in my house connected to the same wow server. When I follow character 1 character 1 and character 4 will start lagging something awful. When I follow character 5 no one disconnects but character 1 lags a bit. When I use just character 1 2 and 3 and follow character 1 nothing happens no one lags no one disconnects.

I can't figure out what the problem is but it didn't happen before this last patch. Its very disappointing.
