WoD already has some good stuff about it imo. The zones were fun to level through, the music and art is all beautiful, and a good number of the raid bosses were good. Just overall it felt a bit light and all the Garrison stuff was super boring.
After the first play through Frostfire Ridge, I thought it would be the best expansion. But after you got through the zones there was nothing left of any real interest. The open world PvE end game was the worst I've ever played in any MMO.
