Did you get to play last night? Do you love it?
FI and I ran the new Blackrock instance (Blackrock Caverns? I think?) three times with a guild group. Thanks in no small part to our 25 complete level 80 dailies and a full 70K XP(!!!) from dungeon quests, we ding'd 81 around 3:30 in the morning and called it "night." We didn't attempt to quest out in the world; there were waaaaaaaaaaay too many people competing for spawns and a whole lot of graphic lag. Some of my guildies are already 82 (we have a DK who will not sleep until he's 85!) and the guild itself is somehow lvl 2.
I'm excited -- as you can tell.
And really sad to be at work right now instead of exploring the new Hyjal!
