Now that we have all the cards, I think inspire deck can become a deck type for paladin, others don't seem as viable.
Dragons should be very playable now, all it took was adding two more with taunt. Dragon mage, warrior, paladin and priest all seem viable to me. Probably paladin will be the best because of consort but mage has ice block and can do some interesting plays. Warrior is similar. Priest I think they have more interesting things to play now, so people won't bother with dragons any time soon.
Hunter, I don't think it will change much from now, same for warlock. Rogue, I have no idea, people have to figure something out with these new cards, I can't say.
Shaman will be stronger than before, I'm not sure how much stronger but definitely better. Pretty good so far.
Neutral legendary cards, there is no probable Dr. Boom insight. Not even close but I really like Chillmaw and will get it. The rest, Justicar could be interesting and those 3 drops are possibly good, the rest seem like filler to me, nothing must have here which is fine.
Class legs, I feel Shaman and Druid both got the best deals followed by warrior, everyone else's is not very playable.
