Did this on the TLP - Coirnav with 70 War - Muramite gear, 70 SK - Some Muramite & some tacvi gear, 70 enc muramite gear, 70 clr murmamite gear, 70 wiz muramite gear, 70 monk w/ some murmamite & some tacvi gear. All have max aa's.
Fight was super easy. Casters were back from stun and still able to cast. Enc had to cast slow 6 times before it landed and 12 before cripple landed. High enough resists that enc ancient dd was resisted frequently and dot would not land.
Clr put down ward and group celestial heal. Basically healed war with pious elixir and a few CH's the whole fight. Clr ended with 80% mana by end of fight.
Wiz had many resists to DD's.
SK HT & DT early. Resisted most sk dots, but, dd's landed and touch of devourer landed with no problem.
The ae stuns are at least 90 seconds a part so it really didnt' bother us during fight. War resisted stun a couple times.
