So, I got MOP last Tuesday and I've been playing the shit out of it. I think it might be my favorite expansion as far as questing goes. It reminds me a lot of WOTLK questing, but with all the phasing and cutscenes of Cataclysm. Also, it feels like they learned something form KOTOR with all the voice acting and companions.
Want to have a good laugh? Go queue up for a random dungeon on a lowbie and watch bad pandas try to tank and heal.
Want to cry? Queue up for Corren Direbrew and watch a healer try to heal it in DPS spec because he thinks it's going to be easy and wipe.
