Why are you concerned about missing server queues and crashes? And over crowded starting zones? And just general chaos?
It will take a couple of weeks (probably) for the Classic servers to stabilize and it will probably take you and your wife and baby the same amount of time.
Go to the hospital and deal with that chaos then come back and enjoy peace in Azeroth.
Play on a laptop! Lol, im stuck out of state on vacation. Its fun, but im taking launch day to play classic. Stuck on a surface using my mobile hotspot… lmao
The real Alpha answer. Let’s be honest, his wife isn’t going to appreciate him being there anyway. Best to set the ground rules now before the baby is even born.
