The answers will probably be predictable but since "best raid" topics keep getting made - what do you think was the worst? I am torn between Trial of the (Grand) Crusader and Dragon Soul. I think ToC/ToGC was technically worse but I always expected it to be a filler raid. Dragon Soul was more of a disappointment because I expected something really cool and epic for Deathwing's raid and instead we got a bunch of reused environments and lame end boss(es).
