3) We found with 2 healers on each tank that penance + atonement was more than enough, used this phase to regen mana
4) There is a lot of damage to heal here, predictable. Mana was an issue - we rotated cooldowns. Visions handled with tremors + heart of fear by a tank. If it went wrong it was spikey raid damage so DR cooldowns helped.
