I like the Musician one that lets you grab a Hymn from the discard pile, Makes me want to sing "Gloria, Gloria, Hallelujah"
That's the one Kurt is getting, too.
I like the Luke hero that makes everyone draw a card, since I likes my A-bom deck.
As to the relative weakness of the abilities, Rob requested average starter-deck level cards. He chose the access ability for all of them. He chose the "draw a card" ability that went on a couple of them and was modified slightly for the gold Luke hero. He wanted the rest of them to be a similar level of ability.
I think a 7/4 green N.T. prophet with site access would be better than most players would assume, but then I know what's coming.
