I think this B&R announcement was probably close to the best possible. And Yeah, I think I'd go back to the original thalia builds too. Blue seems really hard without misstep to help keeping the count up for FoW. Actually I've always thought misstep was better than fow in the blue version, but anyways.
There's still the green force and the ouphe as good cards we got since we went away from the thalia versions and those will probably come in.
I played some matches yesterday after a few weeks with almost no play and wasn't really excited. Matches felt too trivial (blue decks), too stupid (but I guess dredge is not dead yet) or too uncontrollable (karn). But now things look nice again, and maybe even fun!
