Aha, OK!
That would be some coding effort, but at least we can say if that change were made nothing would have to be rebalanced. And I guess UKResistance is bringing up a situation where the trait has impact on the battlefield before target selection and thus affects the target you might choose. I’d argue that kind of behavior was a bad idea but it’s already there so it’s not really worth diving into that topic.
I guess I ask myself if those are meta strats everyone depends on or if being able to back out of a bad cast brings so much good it’s worth the change. Over the years I’ve gotten better about not pushing “Cast” until I REALLY mean it, but I do think for most players this’d be a boon.
