I would first of say that I loved and played world of warcraft ever since 2004 and fell in love with it. I remember some of vanilla WOW... hard leveling, difficult dungeons, no one had a clue on how to play their class. But I am really looking forward to playing legion... like new animations, revamped classes which looks amazing, new dungeons, new pvp prestige leveling system, new mythic raids, easier to play the classes, new artifact weapons, and especially demon hunters are going to added.
I would love to play the new expansion. I have it preordered already.
