That's fair. People also look at chain armor but at least there's one you would use, the one that Bulette drops which gives disengage to allies when you heal them, pretty good on shadowheart. Slap that with blade ward from gloves and it makes Lazael traverse the battlefield unmolested.
I don't remember it dropping anything the last time I killed it, but it was months ago. Still, if I do use it, it would be because of the Disengage on Heal, and not on its properties of being a Chain Shirt. Shadowheart would lose 2 AC wearing it if it's not also +1 AC.
