Well defence doesn't help against a ranged weapon, and your sacreds are nice enough in combat to not really need the extra defence.
I tend to take E9N9 rather than a bless involving water or fire so their survivability gets quite a big boost with +2 protection from berserk, +4 protection from earth bless, 4 reinvigoration and good regeneration. All of their sacreds are fairly strong offensively(recruitables and summons) and have very good survivability(Palankashas have 60 health per square) so I like to boost their survivability from good to great.
