I liked WotLK for many reasons beyond just raiding, especially like it being so much an environment for a paladin...zillions of undead and an evil antagonist that controls them to smite. Liked hearing the crunch of snow under the feet. Liked the cold breath. Liked the blue light filter (liked I liked the yellow/orange one in Sentinel Hill; like the red one in Firelands...sets a perfect mood). Most of all, to be that paladin to burn evil down.
So no bandwagons for me, I like the expansion for what it was for me, not others says it to be.
