It's wild how Blizzard can do something like give Priests multiple cards no one could possibly care about and overlook this. They did SUCH a good job with every other class's curve, and just giving good low-cost options in general. Maybe they assumed everyone would be playing C'Thun Priest?
Here's a card for you. It's practically useless, and your whole class is fucked from the bottom to the top cause we took away the only tools you had. But dont worry, it has great potential that it will unlock when we release the next set of cards. Till then, play dragon priest whether you like it or not.
C'thun priest is ok, but damn is it ever boring to pilot that.
I don't think Herald will see any play. The only way that thing is seeing play is if cards get added in the next adventure that it actually synergizes with, even then I don't know. It still boggles my mind how they made shadowcaster better than a legendary, in the same expansion.
