The main thing I hope is that they don't include the Oath of Treachery. That was probably my least favorite of the UA subclasses, entirely based on the concept.
If they changed the fluff, but kept most of the mechanics how would you feel about it.
I can't really say, because when I read it I found the fluff so bad I blanked out on the mechanics.
I just hope they include the Path of the Storm Herald for the barbarians.
It looked almost perfectly balanced to me.
