After downing them last night I feel that the encounter is a little too RNG in it's current state. I by no means am complaining, but for the random spawns of grounding/tornado on top of raid members (second group of ascendants) seconds before their respective ultimate ability makes the encounter unnecessarily difficult. If it could be a constant model, simply moving, or regulate the spawn to immediately after the ultimate this would save raids from wiping for no reason whatsoever. We had the fight down to a science, but because of completely uncontrollable mechanics, the fight took an hour longer (wipes) then necessary. Thanks for your concern.
