I got to play this box for a bit today and here is what I have seen as a new player...
Its complicated as hell as soon as brilliance hits a enemy.
Until that happens the whole point of this crew seems to be getting those drugs out there. I understand that Neverborn have potentially better choices for 6 points then the Illuminated but for sheer Brilliance spreading it rivals (and I think beats) the Beckoners. I found Graves to be nothing really but a tarpit with a big stick, there to get in the way maybe damage or kill a unit and then die. Lynch is so much fun to play with as well, standard turn went like this: Discard a card for a extra AP, cast Deadman's Hand get those Rams in your hand, Strike twice with his pistol and if possible Pip the Ace each time and watch units drop.
But its very complicated, and the box takes a lot of memorization. I do agree this army needs some healing though.... what about Black Blood Shaman? Its got heals, support abilities, and a badass pulse that give friendly units flurry. Picture Huggy with flurry...
