In order to passively make a class feel more engaging, you would have to organically evolve the mechanics so that there is more of a progression as opposed to a rotation.

The Blood Lily mechanic is an example. It’s not a good one, but it’s a step in the right direction. It would be better if there were another way to expend lilies that didn’t require healing. I find myself using Solace between wall to wall pulls in Ex roulettes because I don’t need them otherwise. If we had, say, a shield we could throw out with a lily, that would be an improvement.

I’m getting off topic, but the point is that the Blood Lily is sort of a passive way of making White Mage feel like they’re more engaged. It gives the class a touch more complexity without making it busy, unlike the new card mini-game Astros have or the lackluster faeries Scholars use.
