F/p Arch mage and bossing

What I do is Legs + Tail at the same time (stand on top of Legs and spam Paralyze), Left Arm, Wings (Left Arm usually dies before Wings so I move to Right after it does), Right arm, and Heads in any order.
I save Infinity for the Arms since getting knocked off those platforms is annoying.

How much do u tank with the legs? And just spam Paralyze? No Eruption or other DoT's? And Yeah when I doing fighting the Right side I notice that if I didnt mist on that small platform close to the boss the eruption doesnt actually hit the Arm. But yeah those are some great pointers. May not do the body tank unless I get +1 I-frame though.
