I think the point is that the cards are supposed to be little more than utility and a bonus, and shouldn't be what you're relying on as an AST. I will admit, though, that getting leveling queues for dungeons where I DON'T have my cards available makes me feel like a weaker CNJ/WHM - but the boosts to the healing spells has helped with that.
And really, since you don't "need" the cards all that much, you can instead just use those Draws to set up for a boss fight if you have Royal Road and Spread. That's what I would do in dungeons like, say, Dusk Vigil. Find a Balance to put in my Spread, then use the other cards randomly until I found a "make it an AoE" card to Royal Road. Then I just lay off the cards until the boss and we have a group-wide attack buff for the first few seconds of the fight and then use whatever cards I pull afterward as appropriate. And then repeat in prep for the next boss.
That or I'll just stick a refresh in my spread, Royal Road a power or time extender and throw out the next card on whoever needs it. All the cards really do is improve the situation somehow, and your performance as a healer shouldn't rely on it. If you NEED that powered-up Bole to keep your tank from dying, there might be other problems in play.
