I’ve always been in the camp of yes I do love the robes and coats but I also like the idea of a caster in armor. Doesn’t have to be full plate like tanks but armored healers are just so appealing. Clerics in other games I’ve played are able to wear chain mail so maybe something akin to that. Robes and coats are great, and I like a good number of them but a little variety never hurts.
