I'm honestly convinced that War is going to get a knee-jerk nerf into the ground after Viking storms the gates with cards like Battlebard and Valknir Flamecaller. The former is a 1-cost 2/2 that'll render the Enrage God Power pointless when paired with Viking Axewoman, and Valknir Flamecaller is an AoE Felid Janissary with better stats.
While I'm certainly quite excited for the CSR, I'm nervous there will be backlash that leads to overnerfing. Fingers crossed for a more tempered response!
Yeah, I could definitely see that happening, even the comments on Reddit are warning against the prevalence of pure face decks which are not very fun to play against. Maybe they'll balance things out before the release, they seem to be adjusting the balance of DO cards so that could change things a little as well.
Here's hopin' they figure out how to slow matches down just enough to leave room for more deck diversity. If they're not careful, we could see archetypes become further entrenched making the next set harder to balance.
