It is pretty awesome the Wayback Machine allowed me to pull the commentary off the old forums. Nerv did a fantastic job narrating the journey through this expansion. Seems like he did pretty OK as a GM/RL as well.
For context, Cataclysm was released on December 7th, 2010.
Blackwing Descent
This section is a little unfinished currently as there was nothing posted on the original forums.
Bastion of Twilight
There was only reference that I could find on this zone; standby for an update from someone that raided this zone.
Throne of the Four Winds
Firelands
As of this writing (Jan 2021), Saji & Nerv STILL talk about Ragnaros. That’s about all you really need to know about this zone.
Dragon Soul
Same comment from above regarding Deathwing.
