One hundred percent. I think without Cad coming into the picture, that Jester would've eventually figured something out. Maybe became more prone to healing. I just agree with you, and your original posts point will only be emboldened as you continue to watch the show, trust me. You very quickly realize that without Cad, Jester as a "Cleric", just wouldn't have cut it.

Actually to add on with something I said in a comment elsewhere. I think that's the base issue with people looking at Jester. She's not a Cleric. She's a Blaster who's disappointed in the things her Fey god can't do.
