I have found the names characters to be hit or miss. The custom spells are great but overall they are very Squishy and expensive for the points.
The fact that only one can be taken in a battalion makes using them competitively very difficult, as you want minimum drops.
As I get deeper and deeper into list building now that all our models are released (or close to release), I am finding that I'd rather spend less points on pricey heroes and put them more into maxing out our squads of rasps and grims and bladegheists.
My meta is not hyper competitive but it is really strong and weak, friendly game lists do not survive well at all. I have all the current models, will get all the remaining models, but for tournament play only a few key units will ever see the table.
