I have not attempted this encounter yet, but its next on my list of things to do. I have a paladin and 4 balance druids as my team. Given the horror stories here, Im thinking at least with my setup that on the first phase. All 4 druids pop a regen/lifebloom followed by a starfall. That should kill them all and pop a regen/lifebloom and treants on the second insanity phase (unless starfalls is off CD). Not to worried about the paladin.
