They talking about more zeal than they show us all the zeal giving cards changed (John Natalis, Drummer, even Ves is instant killed with 5 value).
If more cards have zeal from the start there isn't any necessarity for other means to get zeal. And I bet, Foltest will get his Zeal removed, too, which will be really big buff for NR, because now cards with order don't have to be balanced around Foltest anymore.
2 of the best weapons NR have is nerfed and killed: Foltest's pride, and Flail.
They were actually one of the worst cards NR had, together with Kyan. Thanks to those few cards, the value of a single charge was so huge, that giving a charge to a unit, which got only 1 point out of a charge, was worthless, except if all better units had been removed already.
From what we have seen, they likely changed every engine that gets reliable more than 1 value out of a charge, such that the basic value of a charge becomes 1 and more value is conditional.
By the way, what are the bets on the 4 changed leaders?
-I'm pretty sure of
Foltest and
Adda are changed. Foltest due to Zeal and Adda due to heavy removal no longer having a place in NR
-I doubt it will be Calanthe or Demavend, as Calanthe is too new to be changed in my opinion. And Demavend should be a lot more balanced and healthy now, so I see no need to change him.
-Meve might be too good with more inspiration interactions, but I doubt that she changes
-
Henselt might change as there isn't that much synergy with him and the faction, but he is useful and used
-Woodland and Eredin could be potential candidates too in my opinion
-or
Francesca as she is another leader limitting design space and they are moving away from a big special card archetype and more towards giving each faction a small special card archetype
