Sorry to necro-post...

I'm having a really hard time with Hadronox - 5 paladins (1x prot, 4x ret) on normal at level 73. I think it's the running around that gets me - it's REALLY hard to see if anyone is standing in the poison cloud, and of course there's always that 1-2 second lag between the tank moving and the followers moving to get everyone out of the way.

Anyone have any ideas on how to handle it with 5 paladins?
