The map isn't that big in the beta, most people will find that stuff as a matter of course in regular play. This isn't super secret hidden stuff that requires an extra hour of dungeon running. The full game will undoubtedly be a different story but again, people say the beta is short because it is short. I did everything there was to do in the beta and had a good time but it was not lengthy even for non-speed racer grandpa players like me.
Full size installer so I can copy to take home to install this weekend. Or else I will have to do the long download and wait for hours at home
Sorry man, I don't think they offer that option anymore since the client is an integrated patcher. At least I don't see it on any official Blizzard source
