Deathrattle Demon Hunter was really nice in Stromwind. In the Alterac expansion however, I felt like I can never pressure my opponents out of the  game and the Inquisitors were not good enough as finishers anymore. The new hero card can help solve the finisher problem (just fish for a Deadeye and Performers). Cutting the 4-drops for Drek'thar will help bring maximum pressure to a few turns earlier and only absconds midgame cards that won't really win you the game anyway.
