There is nothing that shows the problem more than this. As the game systems become increasingly larger, it becomes much more difficult to change things. Most people like expansions according to the amount of content that was in each expansion. Timing of expansions and patches is so bad it's unreal at this point. Hopefully now that many graphics systems are updated it will not take so long the next time around. MSV HOF and ToES felt more like 3 raids in that 161 day window vs Highmaul and BRF at 221 days.
