Don't drag the boss during whirles. Get the raid spread out during empowered and each member just face tank one (just like on Animus). If you have chars with taunt (like mistweavers/WW for ex) they can taunt the add to them and then help others kill them. Tell all your raiders to switch to "their" adds as soon as they spawn to get their attention.
Diffuse Magic completely nullifies dmg from whirlings. + RookOn other I just use Guard s AoE reduction trinket. Never had any problems. Don't run away from your healers and you will be fine, and won't require crazy selfheals. Use raid CDs during empowered whirlies, you could use a pally tbh, otherwise your shammy should have enough CDs (spirit link totem etc), warriors shout etc. :?
Before empowered corruption pool 3x chi and touch of death the add that spawns near you. Then if you see some loose - charge them for stun>Keg Smash - should be 50% HP :P
Our first kill with Brm PoV, with ventrillo:

On any subsequent (since we usually don't have the best comp anymore, trying to get as many people through the fight as possible) kill I just kite the adds in p3, here we completely ignored them.
