Yeah towards the end the healing's gotta be so tight lol But as shadow it's gotta be the best fight out there for testing your skill, the cap between a good and a bad SP is going to be about 10k dps, you've got to be disgustingly good at multidotting and knowing what to spend your next GCD on the whole way through till P2.
Its going to be interesting to see this week which is greater, the 5% nerf or the Holy Radiance nerf. I wonder if it will affect any of the HM strats for these encounters.
