Bismarck EX safe zones?

Has anyone been able to identify if there are relative whirlwind safe spots in Bismarck EX p2? I'm asking primarily for the benifit of casters as I've seen them struggle to keep DPS up when whirlwinds and water AoEs are all around them, so just having to dodge the water attacks would obviously be beneficial.

As DRG I've noticed that the whirlwinds rarely move through the blue/green adds or where the tanks are stood but I'm probably just not paying attention to things that aren't affecting me directly.

Just a thought anyhow.

At the South edge around where you jump onto the carapace.
