I queued up solo. None of us had any previous experience. We all discovered the mechanics without asking. We cleared it with 20 minutes left on the timer because some ocassional derps. It's all about communication, assign tasks and perform them as requested. It was an amazing fight, nice music, nice environment. FINALLY A MASSIVE BOSS. I hope the this trend continues in Heavensward.
Edit:
Exactly. This fight requires awareness and teamwork. An impressive nice designed encounter if you ask me.
