World of Warcraft never felt so messy. They really patch everything. Introduce things only to patch them again thousands of times. This game still looks like an alpha and even worse. Mists of Pandaria Alpha was more stable and fun than this. The devs have no idea what they do... even Warlords of Draenor was more fun(lol, never thought i woud write this)... and all that RNG... WoW has become Diablos little dark messy brother.
7.2 makes things even worse... the only thing that was cool from this whole addon was Karazhan, but thats it. I really want Lich King or Pandaria back... *cries*
Took my wife and I around 6 hours to get it all done (2 nights, 3 hours each night)
This is because of queue times, we tried playing against the beginner AI, but the queue time was absurd (15 min per match queue time) - so we just played against intermediate bots, which had a 5 minute queue time, and each match took 20-35 minutes.
It's most assuredly not as easy as some people make it seem, unless you have a way to completely bypass the queue times.
