Blizzard’s “Panda” expansion was released on September 25th, 2012. It would ultimately be the last expansion until Shadowlands that any official raiding would exist.
Finished 5 out of 6 bosses on Heroic before the end.
Heart of Fear
Finished 3 out of 6 bosses on Heroic before the end.
Terrace of Endless Spring
Completed the instance on Normal, but did not kill any bosses on Heroic before the end.
On December 20, 2012, Kinetic officially stopped raiding. There have been various discussions by old school folks to get the band back together, but it has never gotten further than that. It is a testament to the time spent that a handful of us still keep in touch (some more than others).
