Sticking to their own element makes Baldr even worse.
The one hypothetical situation I see Baldr's survivability having an impact on the fight can't even be done by a light SR/SSR team. No light SR/SSR kamihime can inflict a DoT effect. No thunder SR/SSR kamihime can inflict a DoT effect for that matter, so a Phoenix light/thunder team can't do it either.
At least with an Apocalypse team, Amon can be a work around for Beel, Tsukiyomi, Ares, or Acala.
