This post is a little late, but we were able to kill Heroic Aggramar on March 10, 2018 and move on to Argus.
With this kill, it puts us at 26th on the realm for Heroic progression:
Thanks to all of our dedicated members in making this kill happen! We were glad to get some good pulls in on Heroic Argus. We’re hoping to finish our Heroic progression push and move into farming heroic content soon!
