That's probably what I'd say about first day in Northrend if I worked for Microsoft. Consistent is maybe not the word though when I think of it, there's so much variety and imagination in the quests that I just loved it all. It's consistent in that everything is a lot of fun though.
From the starting quests in Valgarde to running Utgarde keep, exploring the Vrykul relationship to humans, discovering a rogue Titan called Loken, running around disguised as a robot, flying as a bird stealing eggs of the cliffs, using weapons to shoot at buildings and bombing pirates. That's a lot of initial impressions.
I played for 4-5 hours in Howling Fjord and I made it to 90% on the experience bar on my way to level 71. There's already death knights at level 64 in the guild and some other classes are level 73, I saw a paladin at 74 before logging which I think might become realm first level 80.
