Hunter is a little bit of a weird one in arena. In constructed it relies VERY heavily on unleash the hounds and other cards that combo with it (starving buzzard, timber wolf, scavenging hyena, etc.) In arena it is impossible to guarantee that you will have any copies of that card for the deck to run smoothly. Talk to anyone who plays at the higher ranks of constructed(5-legend) and I am willing to bet they will agree that UTH is extremely critical to a hunter deck. The classes cards just don't lend themselves well to being used separately, then compared to a mage for instance.

On the subject of Jaraxxus, sure it is a strong card, but you have to be really careful when you play it. Very few good plays can be made with the one mana you have left(assuming you play jarraxxus on t10+) to solidify board position. You are forced to only play the card when you have a solid board position and your opponent can't easily kill you. I am not denying that it is a strong card, I actually think it is a very strong card, you just need to be careful when you play it.
