I think dragon trait and dragon claw could use a nerf.
Don't think a trait that only requires 2 units should completely hard counter any units that rely on spell damage, it makes it impossible to actually run sorcs (outside of dragon sorcs, what a shocker) or elementalists and let's not even get into how powerful all of the dragon units are.
Either nerf or add a magic pen item, better yet have sorcs give their team magic pen instead of an increase in spell power because right now if you're going sorc or elementalists then there's no way to counter if someone is going dragon or gets a dragon claw which automatically makes these traits not worth running outside of dragon sorc shapeshifter or guardian variants just because it uses dragon.
