Think I've posted before inn here but;
1. No carrot to chase. Feels like I've done everything the game has to offer, from decent/average/casual raiding for many years, to collecting pretty much everything.
2. Many bad game designs such as a drop down menu instead off actual content (Get ride off raiding modes)
3. Inn general being bored, and not having a goal with the game.
4. Would I love to play and enjoy the game as much as I did back inn say 2005-2009? Yes, it would be more than fantastic. But until Blizzard leans......
