My guild went to ICC-10 tonight and they had a spare spot for me! I was so excited! In the end we only ended up wiping on Festergut and Rotface a few times but it was really nice to see a new place with my new guildies and also get started on that Ashen rep.
After the raid was called the group decided to go and do Sarth 3D, so Leesah became of the Nightfall. How's this for achievement spam?
I then discovered I only needed Heroic Halls of Lightning for the Champion of the Frozen Wastes title, so off we went to get two titles in one night.
And to finish off, I now have the four-piece Tier 9 set, so all in all, a satisfying night's work.
