Planned Assault is an amazing new Hunter card which I suggest. It's comparable to a much cheaper Solanian's Belongings, and we know how much that quest gets used - it's because abilities are so important, this deck no exception. Another 4 copies of Bestial Wrath? Yes please. Replace my lost Stable Masters/Masters of the Hunt? Sure. Another 4 copies of Snipe? Very handy.
Your quest base is fairly weak for a class that has no inherent draw power. This deck will no doubt lose out on draw power a lot of the time. Call to Arms: Arathi Basin with 14 quests in deck has worked for me in Shaman and Hunter, with Arathi Basin as a solid location. Besides that, you need more quality in your quests, and by that I don't mean replacing themselves like the ones you've got atm, you need ones that draw you extra cards. Rise and be Recognized is an upgrade of Proving Grounds but I think I like Soup for the Soul better, especially in a deck like this.
There's just some thoughts others haven't already mentioned :)
PS This HAS been mentioned but, I strongly suggest you take Black Amnesty out. ;)
