My first completion was through Raid Finder after maybe 4 wipes attempting it with the group. I had a feeling we were able to do it, I watched everyone's movements. I KNEW they had knowledge of the fight. What's funny was, not a single word was exchanged throughout the encounter til the very end. But we completed and all 8 of us got the completion bonus lol.

P.S. I spent 4 hours in a PF group that couldn't pass Add phase. ;/
