Wow i was hoping today would be easier on bandwith. Good Luck and thank you all for a great service. For those with several systems that WoW....my tip for lessening bandwith usage on patch day/s.
Flash drive
d/l all the addons you use and put them on Flash drive then install them on each system. Me I have 6 systems and this simplifies things greatly. No waiting on sites that are getting bombed.....just wish I'd thought of this earlier.
