Haha I'm definitely not rolling my eyes at your character Suku, if anything a Priestess Arcana without some sort of healing would feel a bit off.

I guess the others can be validated as well;
Oberon learns Mediarama in Nocturne
Castiel's some sort of angel thing
Inari could be attributed to harvest

But yeah, couldn't help but sigh since (Self)-healing is something I see almost every time a Persona RP comes up. It's almost as if no one understands the team mechanic and everyone wants to be self-sufficient xD
