At this point it's obvious that they have made the experience grind in Mists of Pandaria much faster than it used to be. I started shooting up levels just casually questing. After only a few quest hubs I was able to queue for the dungeon finder and I started shooting up the levels even faster.
I liked the setting of Mists of Pandaria, it was nice and relaxing, but the quest design and the zone flow wasn't any better than WoW used to be. I mostly did the dungeon finder and that rapidly made me hit the Mists of Pandaria level cap of 90 in one afternoon. I never even left the first zone for questing.
But I had a ton of fun with the dungeon finder. Dungeons were always my favorite part of WoW and it seems like that's still true. I got to sample all the Mists of Pandaria dungeons that afternoon.
Then I was ready to jump into the next expansion, Warlords of Draenor, the next day.
