Simply put... You are not playing your hunter right... Think about mobility!
On the first tier, Post Haste or Narrow Escape are brilliant choices! I prefer Narrow Escape personally, and it will be greatly utilised in my levelling from 85-90. As for raiding, as someone posted before... Morchok, jump disengage enables you to get behind the boulders VERY quick, and even better with it glyphed! I used to use it vs LK for defile, in ToC when you used to get poisoned, Major Homo in FL when your got that bomb thing on you and had to get out from the middle, there are simply LOADS of situations it's useful.
