Disengage

why not just have a ice trap shot

Wish granted!

As of 5.4, disengage can be used out of combat.

Disengage really is an awesome ability, just to be blunt.

Using almost just it alone, I've screwed over more than 15 Flag Carriers in Warsong Gulch just by performing what I call "The Hunter Double-Jump".

I've also come up with a few tricks as well, which I'll list here.

The Hunter Double-Jump

This is my favourite of all the tricks that I use, and is quite simple to pull off.

1. Jump off the edge of a cliff or towards the target you're trying to catch up to, facing towards the target/area you're trying to get to. Jumping allows you to increase the distance you can possibly travel. Also make sure you're in combat first and that there's no hostile Non-Death Grip Cooldown Death Knights around (as they can pull you back to them mid-jump - THIS WILL SCREW YOU OVER).
3. Turn around while in mid-air so that your back is now facing the area/target you're trying to catch up to. The best way to do this is to firstly use your left hand mouse button, turn around with it, hold it down and tap your right hand mouse button at the same time.
4. Right after you've turned around, hit Disengage and watch as you soar over both friend and foe alike, leaving them stupefied as you either catch up or land in front of your enemy, Wing Clip him, Trap him, etc.etc. As far as I know, you can pop a few instant shots at any targets in front of you as you soar.

The Hunter Butterfly Stroke

This, like the Hunter Double-Jump is quite easy to execute, although it require a tad bit more timing. Essentially, it can only be used for travelling reasonably large distances while at the surface of the water, but it most likely beats swimming.

1. To start, remember to be in combat, as always. And also avoid the Death Knights mentioned above. Also make sure your back is towards the are you want to get to. Firstly, press Disengage.
2. You may be wondering why I say press it first. This is because the moment after you press it, you need to jump. From my experience, Disengage seems to have a short "cast time" of about a second before it takes place, so then, once you jump up after pressing Disengage, it should kick in just as you're above water, giving you the same speed and distance benefits as the label says, allowing you to travel over water for a short distance.

And lastly,

The Hunter Parachute

I found out this while in Gnomeregan trying to get my Hydrocane. I'm not going to list any steps here, because it is simply a Hunter Double-Jump, only with perhaps a delay between Steps 3 and 4.

From what I know, Disengage actually reduces all of the extra damage you take from falling down a long distance to zero and then uses the falling point where Disengage took effect as a new starting point for falling. Remember, only use this as a last-ditch resort, and make sure you're in combat. If you can pull it off properly (Provided that my theorycraft is correct), you should be able to land safely after falling from long drops without losing any health where other players would've died.

Well, there's me :D I'd like to see a video of a Hunter using Rocket Boots off a really, really high cliff and a Mage casting Slow Fall on him and seeing how far he gets. :D
