Oulu is the better mitigator but Elimo is more useful. You can have a status cleanser like Ivris to give the status healing or Rinon for healing and light and dark elements or Melchio for the light buff and defense based on attack or 7star Exvehl for the hp buff, ect. Zeldeus attacks instead of healing and boosts BB damage instead of status healing. He has a viable LS which Elimo doesn't have and the BB Damage can help when Roa or Raaga is used instead of Zenia for their uses, preferably Roa for HP and spark oriented LS. Zeldeus does better as a mitigator that what Elimo and Zeldeus both do but Elimo is more useful because she fills many roles. Healer defense buffer status healing mitigator. That's one you'll never see.
