I personally feel Benefic should be on par with Cure and Physick and if that were to happen I would be totally fine if they didn't touch other potency's for AST.

The rng for the card system seems to be a major factor for the AST feeling mediocre in the utility department. Sadly there isn't a whole lot that can be done directly to Draw besides a CD reduction. Besides that I think Royal Road is the skill to look at to solve this since it adds more to that chaotic feel for the AST card system and I personally dislike it in its current form.

My idea for Royal Road is to make it have effects for the sects and not burn cards in order to gain subpar boosts to them.
