You forgot about rule No.1: Never play on patch day.
Really, like always in almost any game thousands of players will try logging in at the same time while others are whining about download times, others will be kicked from the achingly overstrained server, also whining on the forum or leave angry or cynical remarks about how that could be and that the devs should fix this with their godlike server empowerment powers and extra potent hamster food... Next day things will be fixed magically and the forum will return back to normal with complains about new features (which will include me if they left that one specific thing in from beta).
You will be at work and be spared by all this insanity and will be able to play a much less overrun and thus more stable game.
