It’s hard to come up with a specific niche for multiple preservation characters that separate them from each other so that they don’t all just “shield” you. Fu xuan offers cr,dmg share,and a bit of heal, Aventurine offers a huge shield and follow-up along with cdmg taken debuff. There isn’t much for the devs to do about 4 star preservations because only difference would probably be ways of applying shield and a small buff. Now an interesting concept that they will definitely release in the future is a preservation who can reflect dmg.
