Well they fixed garrison post, so I think they just want to do lots of playtesting of fixes to make sure they don't have to errata a card twice. Also I think warsledge, Bridge Troll, and Akiro's battle Cry are all cards that may not be in top decks but are potentially good cards.
There's tons of other cards that aren't quite good enough to be playable, such as Susruko, or Tarok the sky hunter, but no one complains about them because the beastmaster isn't a weak mage. The real complaint of the original post was that the warlord is weak, and that has been fixed.
