Yep but I've seen a lot of raids with 2-3 people fail because none of them brought Andromeda so they couldn't help each other out when someone got dead ended by RNG or just straight up damage. There was even one I was in with 5 people and nobody swinging cause everyone was hurt - I was the only one with Andromeda so it was only after my heals that people could swing, and then we all dead ended after awhile as my group eventually got pressured down and none of them had heals to complement it. Dead ending could all have been avoided with Andro/Cass.
