Yeah Samara is the best for the biotic bubble one I believe. Miranda or Jacob or Garrus Maybe? are great for the second team lead. Legion I think is the best for the vents. I don't remember it all, it's been a while. And if you don't have their loyalty from their missions, they most likely will die regardless.

I lost uhhhh Zaeed. He's one you didn't get from a DLC, bubba.
