Wrath and BC both had less to do than any of the previous four expansions, and don't get me wrong, I absolutely loved both of them. In some aspects less is more because it lets players do what they enjoy doing. Wrath and BC I did tons of world PvP because I did not have to spend times of time on power progression systems. Only argument you can make for Wrath having more content is multiple locks on a single raid and BC you had attunements for raids (which I honestly thought was great.)
