That’s true, with Avenger of Cairn and +maximum resistances from it you can take almost 2x less damage from aether as example which matters a lot in deepest shards. It’s currently best amulet you can get for soldier class if you go for record 
It’s also nice to have another source of damage reduction except war cry like Vire or Empyrion devotion, even with Warborn helmet to avoid one shots.
