Lady Amandine's Maidens

I've only run Haukke twice since release and it seems like the last fight got buffed. I'm fine with that but I'm kind of lost when it comes to the maiden adds during the last boss. One run the damage they did was pretty high but I managed to heal it just fine but second run I practically fell over dead when they spawned. There's no red circle so I'm not sure if I can avoid whatever fire attack they're throwing around.

Any tips would be helpful.

Yes and No. Yes, it got buff from phase 2 beta but got Nerf from phase 3.

You'll likely to die if tank and dps ignore them. Just tell them to get those adds off you.
