Descending the platforms at Soa seems to be surprisingly hard. My last two attempts at it through group finder have failed because half the people died when descending. I'm not quite sure if it was the healers that didn't heal enough, or the other people who didn't stay where the healers could heal them.
How... just how??? It's 2 mechanics. Jump down to the next level when the platforms are there and kill off the devices... I could only hope they would know how to pay attention to their own hp to see if they need healed or not.
