Neverborn are my first love in malifaux first edition, and I have been playing them exclusively in the beta. I have used Pandora the most and she feels about right, althought I do have a concern that she could still be a bit of a neg play experience against low Wp masters and crews. When I used her against McMourning she and candy had him paralyzed for three turns which was frustrating for my opponent. I also used the fudge state upgrade for the first time and managed to make quite a few of his minions insignificant. So she still has a lot of "no you can't " abilities. I think she is nowhere near as bad as last edition, but still think I will have to be careful that she doesn't wear out her welcome.
Used Z twice, she feels just right. Love the fact that her two limited upgrades are both good, and I can honestly say that neither is better than the other and will depend on what you want to achieve. Lilith is the master I am struggling with, just can't get her to work. Barbaros is a riot to use, but I have to admit that the rest of the nephilim feel weak and fragile. I still think a sprinkling of companion in the crew would be nice. Two of her spells are CA 5 so I really havent tried to use them much as AP are so precious in this edition I can't waste a action on a spell that most models have a good chance of resisting. Having them target defense would make these spells a bit more reliable without raising the casting value.
Last game I played I used lynch. Man is he and his crew good. I can really see myself using him alot. Clicked with me straight away.
Anyway i rambled too much, overall the Neverborn are great fun to play, have retained their flavour, and are not as OP as before. Good times ahead folks.
