So after 15 minutes of 20 level 50's smashing Odin in the face... We managed to reduce him to 1/50th life. I'm guessing he cannot be completed as of now? He was dealing 14,000 damage a hit.

Has anyone fought him yet? What do you think?

The one strategy I think may work would be one or two tanks who can hold agro whole 3-4 BLM's cast manawall (nullifies 2 physical attacks) on the tanks while 20-30 DPS chars straight up focus on damaging.
