It might be a small thing, but my favorite thing is probably the panda /silly and /flirt emotes. The phrases and inflections in the voice are just perfect =)
The smooth questing transition from starting zone and beyond. Great scenery throughout Pandaria. LFR is a great way to familiarize yourself with raids and a good alternative to dungeons, which were enjoyable the first few times through. My panda windwalker was super fun to play from level 1 to 85!
