I don't understand all the hatred towards Cataclysm. I personally loved the heroics and the first 2 tiers of raid content. Was Dragon Soul truly so awful that it ruined the entire expansion for people? Did the world revamp leave a bad taste in player's mouths because it consumed precious content development time?
Cata, as a whole, needed to happen and Azeroth is a better place now because of it. The expansion had a major impact on WoW for the greater good such as: huge steps were taken towards improving the questing experience, flight was introduced in Azeroth, and the design and artwork throughout the world saw great improvements.
What are your thoughts? Why was Cataclysm such a bad expansion in your eyes?
