It looks like this is normal mode, so the heal just doesn't matter (you have to deal almost as much damage to the add as it heals, plus target swapping, stunning, slowing, etc. lower DPS and you lose cleave damage if they're spread out). Apart from that, if you don't interrupt the priest, she continues casting from range. Once she's empowered, you can have someone interrupt her and she'll run into range for cleaving. Once the empower fades, you can not interrupt her and just pull the group away again.
For the stun, it looks like he just ate them. He was stunned 5 times for the full duration. He probably popped a defensive before getting stunned and then they threw external cooldowns on him.
Besides the rotation stuff already mention a few times, i would change a few things about the gear/enchanting. Just remember that this is only what i would do!
Weapon: Change from River's Song to Dancing Steel or Windsong, dodge is baaaaad.
Shield: Change from Parry to Mastery.
Bracers: Mastery to Strength or LW Stam
Boots: Mastery to Haste - i do not think the movement speed is worth it compared to the extra haste.
Some generel stuff: Dodge and parry is no good and i wouldnt use the Glyph of Hammer of the Righteous on any fight.
Sorry had not followed up on this at all ><
We just stack up completely and aoe the crap out of everything unless its the empowered add. Our pallie tank just soaks the frost stun! He will pop a cd and or call out for one right as he gets stuned.
This is how it looks when we do it :
