Limbus suggestion.

Hope he doesn't mean using your 2hr within 2 seconds of the mob using it, or by using /kneel. We still don't have any way of avoiding PW'd Astral Flow unless there's a hidden thing to avoid it that nobody knows so far(maybe something ridiculous like using Soultrappers on lamps or something dumb like that). Perfect Defense doesn't count.

I thought having an Outside-of-alliance player Diaga the Avatars when they popped and running worked? Or is it an "Anyone in range is hit" Astral flow?

Could have sworn i saw a strategy revolving around outside RDM diaga'ing the Avatars... Was a long time ago however.
