This Exploit requires a Hunter of lvl 20 and above with the skill: Disengage.
Ok this'll be hard to explain, but here goes.
To get this right, you'll have to try it a few times, but once you get it, it's easy.
1. Get to a high place, I suggest Thunderbluff: Hunter Rise, close to Dummies.
2. Attack the dummies and get into combat.
3. Jump off the cliff and about 10 yards before you hit the ground, hit disengage. Your fall dmg will now be determined from the height of where you used Disengage
Tip: Do not wait till you nearly hit the ground, it always takes a while before disengage goes off, therefor you might die before the actual disengage jump.
Now you might ask yourself: How's this useful?
We all hate those people who use flying mounts to avoid PvP Combat, but we hate those the most that get off with 10% HP.
Well that's no problem anymore! Just fly after him, dismount -> Kill Shot, wait till you're close to the ground and disengage -> no fall dmg.
