Honestly, I think one of the problems is that there's no real way to counter battlecries in the game at the moment. Sure you can force out a random minion with Hecklebot or Duel!, but otherwise the best you can hope for is to play around battlecries whenever possible. It would almost be worth them printing a tech card to counter opponents' battlecries before they happen to restrict the power of classes like Shaman that have so many impactful ones available.
