Actually for each raid boss, different squad is good for the sake of efficiency. But to put it simply what you really need the most is MITIGATOR(yours are Dolk, Krantz), STATUS AILMENTS NULLIFIER(I don't think you have it, besides Dolk. He just cleans them though), HEALER/BC HC drop booster(again, I think either your Dolk or Krantz settle it).

Read some from this Essential Squad Compositions by Linathan, hope it helps
