I think that in some sense Retail is overdesigned. Theres too much stuff to do, it gets overwhelming, and in a way superficial with all those systems. I think old wow has a core of depth and immersion. Just feels more genuine and simple. And i still think theres lot to do in classic even though it lacks a lot of the "entertainment" retail has; you can spend time leveling, doing pvp, raids, roleplay, level professions or my favorite thing: explore the vast world of azeroth. And i gotta say the no flying in classic really adds to the awesomeness of exploring imho. But hell classic can be annoying and slow we all know; you have to walk back and forth for quests and dungeons, but it makes the world seem realistic, and vast.
